Version for R 1.6.0
Universal GNU Fortran 4.2.3 for Mac OS X 10.4 and higher. It is necessary in order to build R packages from sources that contain Fortran code. Unlike many other builds, this is a fully universal build of GNU Fortran that uses Apple's driver and supports all target architectures (i386, ppc, x8664 and ppc64). Officially, the operating system that was available on that Mac at the time that you bought it is the oldest version of macOS that can run on that Mac. It's likely that an older OS won't include.
S. M. Iacus
Changes and bug fixing specific to this version:
- new scripts to build packages: makeAdd, makeRcmd, makeBio all the makefiles have been moved to src/macintosh/makefiles folder
- implemented the Quartz device (when running under OSX only)
- brand new worskspace browser, see Tools menu
- added and/or fixed internally mkdir and rmdir. Now unlink(), dir.create() etc work correctly
- html help handled via applescript. More stable and almost browser independent
- improved applescript support
- implemented browseURL
- implemented tempdir and tempfile according to Unix/Windows behaviour
- Date arithmetic fails (PR#1819). This bug have been partially fixed. Arithmetic is fine now but there is still a problem with the TZ (Time Zone) settings.
- fixed a bug in Locator of Macintosh device. Now it is possible to interrupt it.
- From this version WasteLib 2.1x is required

NEWS
There are several enanchements in this release. Most of them concern the user interface of R application but one of the most important novelty is that now
R runs both on MacOS and MacOS X using Carbon technology. This means that when you run R from MacOS X it run natively under the new System without calling the Classic Compatibility Module. The use of R under MacOS X takes lots of advantages starting from the new Aqua look.
As this version is based on the new Carbon technology some new bugs can appear that we were'nt able to found before releasing R officially.
Any feedback is then welcome at stefano.iacus@unimi.it

About R windows.
Normally R opens windows to let 80 character/columns to be displayed. The size of the windows is calculated on the basis of the size of the font used.
For non fixed fonts the algorithm can fail so the window can result a bit larger or smaller then needed.
R windows are opened in cascade for each class (edit windows, file show windows and graphic windows). This functionality does not work on MacOS X yet.
APPLE SCRIPT SUPPORT
From release 1.3.1 R has partial support for AppleScripts. This means two things: you can run applescripts from inside R using the command applescript() (see the corresponing help) or you can ask R to run commands from and applescript. The directory 'scripts' in the main R folder contains two examples of applescripts. What follows is an example of applescript that interacts with R.
set CommandLine to 'R.Version()'
try
tell application 'R'
activate
with timeout of 90000 seconds
cmd CommandLine
cmd 'Sys.getenv()'
end timeout
end tell
end try
Where cmd is the applescript command in the R dictionary that is used to tell R to execute an R command in the R Console. The syntax is cmd<command string>, where command string have to be in quotes. Actually, the output of the command is not sent back to the application that is calling R but to the R Console.
EXTERNAL EDITOR INTERACTION
From release 7.4.1 of the famous Alpha editor, there is a (tcl) mode called S+/R.
When you open a file in Alpha with the extension '.s' or '.r' this new mode will be installed and you will in the Alpha menu bar the 'S+/R' menu. Of this menu you can use 'Process File' or 'Process Selection' to interact with R. By default Alpha sends an `open' command to R and by default R opens a file in a non editable window (equivalent to the `File Show' menu). If you want R to source a file you should modify activate the option 'OnOpenSource' that is set by default to 'FALSE'. You can change this at runtime running via the Config/OnOpenSource menu or accessing the Preferences pane. The latest version of Alpha can be found at ftp://ftp.ucsd.edu/pub/alpha/
MEMORY
Under MacOS you should reserve a fixed amount of memory to each application. As R is just an application, you need to set this to a bigger amount of memory if for some reason R went out of memory. To do this, go to the Finder and select the R aplication icon. Then with CMD+I key obtain the Information for R. Select 'Memory' and the fix the amount of memory you need. Under MacOS X, there is no need to reserve memory to R. R will use as much memory as it needs.
SPECIFYING OPTIONS: the Preferences pane
The Preferences pane allow you to configure a bit R GUI and behaviour. You can set the tab size in your edit windows, the font type and size of text windows and R Console as well as the colors of the text in R Console. You can also specify a particular font for the graphic device and the resolution of the graphic device. Finally you can specify if R should accept User breaks (CMD+. or Esc). If this option is enabled R is a bit slower. You can instruct R on what to do when a file is opened: source it or simply show in the internal viewer.
Take care that under MacOS R creates a file in the Preferences folder of you System Folder. If you switch to MacOS X than, this folder is no longer the default Preferences folder so you have either to move th 'R preferences' file to '~user/Library/Preferences/' directory or reset the preferences. If you have different logins under OS X, remember that each user should set its own preferences.
SPECIFYING ENVIRONMENT VARIABLES: the .Renviron file
In this file you can specify some of options or environment variables. This is not standard for general MacOS/X applications but has been implemented for compatibility reasons. If you don't need to set environment variables you can ignore what is in this file.
The environment file is used by R application both to simulate the enviroment on a standard Unix or Windows system.
You can always use 'Sys.getenv()' to see which variables are set to some values.
The .Renviron file looks like this: an option is a 'Rkey' with its 'keyvalue' that you can specify in new separate line as follows RKey=keyvalue. Consider that RKey=keyvalue and RKey = keyvalue are different, that means that blanks/spaces are significant. 'RKey' and 'keyvalue' are case sensitive. A symbol '#' at the beginning of a line means that this is a commented out line.
You can find more details on that in the .Renviron file itself.
THE NEW USER MENU
The user has now the ability to create a menu with several menuitems, up to 99, where to keep preferred R commands.
With the commands add.menu.cmd('label','R_command') the user adds a menuitem named 'label' to the User menu. When the command is selected from the menu, R executes the command 'Rcommand' associated to it. The User menu is created dynamically, so that user will never see it if he does not add any item to it.
Several functions to manipulate the user menu are previewed:
| get.menu.cmd('label') | returns the R Command associated to menu item 'label' and the corresponding menu number |
| get.num.cmd(menunum) | returns the R Command associated to menu item number 'menunum' and the corresponding menu label |
| del.menu.cmd('label') | removes the menu item 'label' from the User menu |
| del.num.cmd(menunum) | removes the menu item numbered 'menunum' from the User menu |
| del.usr.cmd('label') | removes the whole User's menu |
| add.menu.cmd('label','RCommand') | adds a menu item to the User's menu, if any, with associated the R command 'RCommand' |
R HELPERS
* If you want to use an external editor we suggest you to use Alpha version 7.4.1 or newer that contains a S+/R mode. Alpha home page is located at http://www.kelehers.org/alpha/.
SYSTEM REQUIREMENTS
To run the R application you need at least 42MB of free memory for the application itself you work under MacOS but there is no limitations under MacOS X as virtual memory is always on.
You need the latest version of the CarbonLib library from Apple. At the time of this release, version 1.4 is the current non developer release. Normally it is included in System 9.2 and X.
Now R needs the f2cLib shared library to run. This library is distributed with R but in case you miss it you can found it here.
The minimum System version release is 8.6 (+ CarbonLib library).
You need the WasteLib library. This library is distributed with R binaries.
You need the zlibLib library. This library is distributed with R binaries.
KNOWN BUGS
- This version of R and Adobe ATM are incompatible. We are looking at the problem. The solution is that you should switch ATM off before running R. (Thanks to R. Gill for feedback on this bug)
- Internet functionality is not available yet. We are working on this.
- Mathematical expressions are not yet well spaced moreover, mathemathic symbols are not rotated.
| Q | How can I manage invisible files under MacOS X ? |
| A | Under Unix it is typical that invisible files are files starting with a '.' (dot) in the filename. MacOS X conforms to this convention. So it could happen that your preferred editor doesn't allow you to open and or write files like .Rprofile or .Renviron under MacOS X (this is the case of BBedit as reported by one user). You have several options: one of this is to a file like 'some_file' with your editor or R, and then use the system() command to change its name as follows system('mv some_file .some_file'). Then use system('ls -al') to see if all went right. |
| Q | On exit: Why I can't save the workspace image via file dialog under MacOS X ? |
| A | As before, files starting with a dot, such as '.RData' cannot be managed directly via standard dialogs (you can see invisible files but you can't specify them as filenames !) To save the workspace image, you can either save it with a different name (e.g. 'RData', but in this the workspace image will not be reloaded the next you start R), or you save it beofre quitting R: type 'save.image()' from the R Console and then 'q()' replying 'n' when R asks for 'Save workspace image? [y/n/c]:'. |
| Q | How can I work on a separate directory for each of my projects? |
| A | Under Unix you usually create a directory, go into it and launch R. Under MacOS you can create a directory and put all the files that you need there. You then (or before) run R in its own directory and use the menu item 'Tools->Change Working Directory' to change the current working directory to directory you have created. You can then work as you do in Unix. You can save/load workspace image to this directory, as well as the command history files. You can then reload these next time you work. |
| Q | How can I interrupt lengthy operations or output ? |
| A | You can now use the standard Macintosh control break sequence, that is you should press 'Cmd option' and '.' (dot). This will interrupt any R loops. The 'Esc' key gives you the same result. |
| Q | How can I change memory settings for R ? (MacOS pre X only) |
| A | You cannot use the standard settings as on other platforms. You should assign memory to R from the Finder/Information dialog for R application. See Section 'Memory' above. |
| Q | When I use to send R output to a file like 'my_file', R seems to work on this file but I cannot find it. What happened ? (MacOS X only) |
| A | On MacOS X it is important to specify correctly the file names. If you want the file to be created in your current working directory you have to put a ':' before file name, such as ':myfile' otherwise the file will be created as '/my_file', i.e. in the root '/' directory. This is in particular important when you specify directories relative to your current working directory. |
REMERCIEMENTS
I would like to thank among the others (only few I can remember due to my brain volatility..) some of the people who have contantly sent me feedback on this Macintosh port of R or simply suggetested me some possibile directions. So, merci, in random order, to P. Macdonald, P. Flint, R. Gill, K. Pflugshaupt, J. DeLeeuw, G. Sawitzki and half of the R-Core.

To do this, go to the Finder and select the R aplication icon. Then with CMD+I key obtain the Information for R. Select 'Memory' and the fix the amount of memory you need. Under MacOS X, there is no need to reserve memory to R. R will use as much memory as it needs.
SPECIFYING OPTIONS: the Preferences pane
The Preferences pane allow you to configure a bit R GUI and behaviour. You can set the tab size in your edit windows, the font type and size of text windows and R Console as well as the colors of the text in R Console. You can also specify a particular font for the graphic device and the resolution of the graphic device. Finally you can specify if R should accept User breaks (CMD+. or Esc). If this option is enabled R is a bit slower. You can instruct R on what to do when a file is opened: source it or simply show in the internal viewer.
Take care that under MacOS R creates a file in the Preferences folder of you System Folder. If you switch to MacOS X than, this folder is no longer the default Preferences folder so you have either to move th 'R preferences' file to '~user/Library/Preferences/' directory or reset the preferences. If you have different logins under OS X, remember that each user should set its own preferences.
SPECIFYING ENVIRONMENT VARIABLES: the .Renviron file
In this file you can specify some of options or environment variables. This is not standard for general MacOS/X applications but has been implemented for compatibility reasons. If you don't need to set environment variables you can ignore what is in this file.
The environment file is used by R application both to simulate the enviroment on a standard Unix or Windows system.
You can always use 'Sys.getenv()' to see which variables are set to some values.
The .Renviron file looks like this: an option is a 'Rkey' with its 'keyvalue' that you can specify in new separate line as follows RKey=keyvalue. Consider that RKey=keyvalue and RKey = keyvalue are different, that means that blanks/spaces are significant. 'RKey' and 'keyvalue' are case sensitive. A symbol '#' at the beginning of a line means that this is a commented out line.
You can find more details on that in the .Renviron file itself.
THE NEW USER MENU
The user has now the ability to create a menu with several menuitems, up to 99, where to keep preferred R commands.
With the commands add.menu.cmd('label','R_command') the user adds a menuitem named 'label' to the User menu. When the command is selected from the menu, R executes the command 'Rcommand' associated to it. The User menu is created dynamically, so that user will never see it if he does not add any item to it.
Several functions to manipulate the user menu are previewed:
| get.menu.cmd('label') | returns the R Command associated to menu item 'label' and the corresponding menu number |
| get.num.cmd(menunum) | returns the R Command associated to menu item number 'menunum' and the corresponding menu label |
| del.menu.cmd('label') | removes the menu item 'label' from the User menu |
| del.num.cmd(menunum) | removes the menu item numbered 'menunum' from the User menu |
| del.usr.cmd('label') | removes the whole User's menu |
| add.menu.cmd('label','RCommand') | adds a menu item to the User's menu, if any, with associated the R command 'RCommand' |
R HELPERS
* If you want to use an external editor we suggest you to use Alpha version 7.4.1 or newer that contains a S+/R mode. Alpha home page is located at http://www.kelehers.org/alpha/.
SYSTEM REQUIREMENTS
To run the R application you need at least 42MB of free memory for the application itself you work under MacOS but there is no limitations under MacOS X as virtual memory is always on.
You need the latest version of the CarbonLib library from Apple. At the time of this release, version 1.4 is the current non developer release. Normally it is included in System 9.2 and X.
Now R needs the f2cLib shared library to run. This library is distributed with R but in case you miss it you can found it here.
The minimum System version release is 8.6 (+ CarbonLib library).
You need the WasteLib library. This library is distributed with R binaries.
You need the zlibLib library. This library is distributed with R binaries.
KNOWN BUGS
- This version of R and Adobe ATM are incompatible. We are looking at the problem. The solution is that you should switch ATM off before running R. (Thanks to R. Gill for feedback on this bug)
- Internet functionality is not available yet. We are working on this.
- Mathematical expressions are not yet well spaced moreover, mathemathic symbols are not rotated.
| Q | How can I manage invisible files under MacOS X ? |
| A | Under Unix it is typical that invisible files are files starting with a '.' (dot) in the filename. MacOS X conforms to this convention. So it could happen that your preferred editor doesn't allow you to open and or write files like .Rprofile or .Renviron under MacOS X (this is the case of BBedit as reported by one user). You have several options: one of this is to a file like 'some_file' with your editor or R, and then use the system() command to change its name as follows system('mv some_file .some_file'). Then use system('ls -al') to see if all went right. |
| Q | On exit: Why I can't save the workspace image via file dialog under MacOS X ? |
| A | As before, files starting with a dot, such as '.RData' cannot be managed directly via standard dialogs (you can see invisible files but you can't specify them as filenames !) To save the workspace image, you can either save it with a different name (e.g. 'RData', but in this the workspace image will not be reloaded the next you start R), or you save it beofre quitting R: type 'save.image()' from the R Console and then 'q()' replying 'n' when R asks for 'Save workspace image? [y/n/c]:'. |
| Q | How can I work on a separate directory for each of my projects? |
| A | Under Unix you usually create a directory, go into it and launch R. Under MacOS you can create a directory and put all the files that you need there. You then (or before) run R in its own directory and use the menu item 'Tools->Change Working Directory' to change the current working directory to directory you have created. You can then work as you do in Unix. You can save/load workspace image to this directory, as well as the command history files. You can then reload these next time you work. |
| Q | How can I interrupt lengthy operations or output ? |
| A | You can now use the standard Macintosh control break sequence, that is you should press 'Cmd option' and '.' (dot). This will interrupt any R loops. The 'Esc' key gives you the same result. |
| Q | How can I change memory settings for R ? (MacOS pre X only) |
| A | You cannot use the standard settings as on other platforms. You should assign memory to R from the Finder/Information dialog for R application. See Section 'Memory' above. |
| Q | When I use to send R output to a file like 'my_file', R seems to work on this file but I cannot find it. What happened ? (MacOS X only) |
| A | On MacOS X it is important to specify correctly the file names. If you want the file to be created in your current working directory you have to put a ':' before file name, such as ':myfile' otherwise the file will be created as '/my_file', i.e. in the root '/' directory. This is in particular important when you specify directories relative to your current working directory. |
REMERCIEMENTS
I would like to thank among the others (only few I can remember due to my brain volatility..) some of the people who have contantly sent me feedback on this Macintosh port of R or simply suggetested me some possibile directions. So, merci, in random order, to P. Macdonald, P. Flint, R. Gill, K. Pflugshaupt, J. DeLeeuw, G. Sawitzki and half of the R-Core.
