If your copy will be "private" you can use --disable-R-framework and set rhome at install time to wherever you want (or alternatively you can set the path of the framework if you need it).

It is possible, albeit convoluted. The easy part of to modify R_HOME - you simply do that in the R script. The harder part is that all binaries have absolute paths to libraries inside the framework. You will have to go through every single binary (package, module, executable) and change all paths to your new location using install_name_tool. To be honest, given how ancient your R is I wouldn't even bother and just keep it in its 2.5 folder since chances that it will clash on user's machine are close to zero. But if you choose to tackle this, you can take inspiration from this script (it uses @rpath which is a bit more flexible but requires more support from binaries): https://svn.r-project.org/R-dev-web/trunk/QA/Simon/R-build/rpath.sh An alternative fix is to use DYLD_LIBRARY_PATH to prepend your new location of libraries. It may or may not work, depending on what you use from R. It is a bit fragile but is fairly easy to do so you can test whether it works for your particular setup of using R. > However, I'd also like this to work, even when I move this to a different > location on my file system. I appreciate some guidance on this last step. > That is actually close to impossible unless you are ok with giving up package installation. The problem is that a) binary package have full paths encoded and b) if you compile a package it will get full path and they need a path to compile. However, if you are shipping a "fixed" R that will not be modified by adding packages, you can use the same idea as above with the special @executable_path prefix. You'll need to perform some gymnastics to infer R_HOME in the R script since it will by dynamic, but it's possible -- the following patch will give you an idea: https://svn.r-project.org/R-dev-web/trunk/QA/Simon/R-build/R-rpath-diff The executive summary is that what you want is possible, but not really easy.

Re: [R-SIG-Mac] Multiple R versions: set Current via symbolic link: permissions?
That thread does help and it provides enough information to solve most of my problem. However, it is not clear to me how to change the R_HOME directory so that it is not in the /Library/Frameworks/R.framework directory. This is important to me because I am providing a tool which will automatically install R and I don't want my tool to replace an existing version of R. I tried building from source, and immediately ran into two problems: 1) I don't know enough to know how to configure my build so that it doesn't use the Frameworks location 2) specifically to R 2.5, which I need, I get compiler errors. I'd like to simply take apart the framework build I get when install from the R-2.5.1.dmg. However, I'd also like this to work, even when I move this to a different location on my file system. I appreciate some guidance on this last step. Thanks, Peter ___ R-SIG-Mac mailing list R-SIG-Mac@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-mac

I have looked in vain for a clear explanation of why there can be one and only one 'Current' version of R running at a time. That is simply untrue, and would be crippling for the R developers if it were true. Assuming you have multiple R versions installed, all you need to do is to invoke their 'R' scripts directly. There is a problem caused by the way Simon installs these scripts in frameworks, so e.g. /Library/Frameworks/R.framework/Versions/2.13/Resources/bin/R starts #!/bin/sh # Shell wrapper for R executable. R_HOME_DIR=/Library/Frameworks/R.framework/Resources but all you have to do is make a copy and change that to e.g. R_HOME_DIR=/Library/Frameworks/R.framework/Versions/2.13/Resources [Which is in the thread mentioned.] And of course, no one said you have to use that particular build of R, and for serious users of command-line R a personal build will be more convenient (just like any other platform). If you have packages which use compiled code they are tied (on OS X only) to a particular 2.x.* set of R versions, but you can overcome that easily enough by using different library directories for different versions of R. You can dig up some info from this thread: https://stat.ethz.ch/pipermail/r-sig-mac/2011-September/008582.html I believe the take home message is that if you want to do this (running different R versions *simultaneously*), you can do some symlink mojo (you'll find links to examples in that thread) that will let you do so, and (for the most part), it will work. The problem arises when you have to install R packages that need be source compiled. This limitation holds if we are talking about running R versions that were released as binaries on CRAN (I'm not sure if this is true when you compile R as a framework build yourself (but my guess is that it will still be a problem in that scenario, as well)). I can link you straight to the email that says that (w/ more details), but you'd probably better be served by just going through the entirety of that thread. Hope that helps, -steve -- Brian D.

Re: [R-SIG-Mac] Multiple R versions: set Current via symbolic link: permissions?
I, too, would like to run multiple versions of R, via command line, on Mac OS X. I have looked in vain for a clear explanation of why there can be one and only one 'Current' version of R running at a time. After running the installer, I manually edit the /Library/Frameworks/Versions//Resources/bin/R script. Replacing the '/Library/Frameworks/R.framework/Resources' with '/Library/Frameworks/R.framework/Versions/2.14/Resources'. Is this sufficient to support multiple versions of R on a Mac?

Note that for symlinks you'll need extra -h in chown otherwise you're changing ownership of the target not the link. If in doubt (ie., you messed with permissions before), run sudo chmod g+w -R /Library/Frameworks/R.framework Cheers, Simon > On executing R2.13 in the terminal, I get: > rm: /Library/Frameworks/R.framework/Versions/Current: Permission denied > ln: /Library/Frameworks/R.framework/Versions/Current/2.13: Permission denied > > If I chown Current, I still get: > rm: /Library/Frameworks/R.framework/Versions/Current: Permission denied > > I (bad) solution is to put in "sudo" in the alias... > > How is it done correctly? > > Cheers, > > Marius > > PS: I also posted it for future reference, I've only found the idea of using > ln -s on the help pages/FAQ, but not how to get around the permission issue. > ___ > R-SIG-Mac mailing list > R-SIG-Mac@r-project.org > https://stat.ethz.ch/mailman/listinfo/r-sig-mac > > ___ R-SIG-Mac mailing list R-SIG-Mac@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-mac
Re: [R-SIG-Mac] Multiple R versions: set Current via symbolic link: permissions?
Ah, I see. On my system, I'm able to create a symlink within /Library/Frameworks/R.framework/Versions -- the directory is owned by user "root", group "admin", and my user account is also in group "admin". Hope that helps... Cheers, Martin On 11 October 2011 11:46, Marius Hofert wrote: > Hi Martin, > > thanks, but I'm aware of that.

Hi Martin, thanks, but I'm aware of that. I was looking for the command-line approach :-) Cheers, Marius On 2011-10-11, at 12:43 , Martin Ellis wrote: > I'm not sure if you're already aware of RSwitch (available at > http://r.research.att.com/), but it seems like it might be useful for > what you're trying to do. > > Cheers, > Martin > > > On 11 October 2011 11:24, Marius Hofert wrote: >> Hi, >> >> I have multiple R versions installed and would like to switch between them >> via setting the symblic link "Current".

Re: [R-SIG-Mac] Multiple R versions: set Current via symbolic link: permissions?
I'm not sure if you're already aware of RSwitch (available at http://r.research.att.com/), but it seems like it might be useful for what you're trying to do.
