After installing the Mac GUI R: If I navigate to the "Applications" directory in the Mac Finder file browser, and <Control>-click (or right-click) on the R.app icon, a contextual menu pops up - I select "Duplicate" and a second "R copy.app" is created. I can then double-click to run that and have two copies of R up and running with the Mac R gui interface.
I have yet to uncover any problem with doing this, Simon Urbanek can hopefully comment if there is any problem with this. So this appears to be one way to allow multiple instances of the same version of Mac GUI R to run. Alternatively, if I run the following command from a "Terminal" window $ /Applications/R.app/Contents/MacOS/R & $ /Applications/R.app/Contents/MacOS/R & $ /Applications/R.app/Contents/MacOS/R & I get several instances of the same version of the Mac GUI R up and running. So these are two methods I use to invoke multiple instances of various programs on my Mac. Of course you need to be clear about where each instance is writing its data, so for example if you quit and save the R session data objects to the default .RData file, you will overwrite the .RData file from another session instance as they will all have the same working directory - so you need to save results carefully. Other than that, I have not seen any problems with running multiple instances in these ways. If anyone knows of other potential problems, I'd appreciate hearing about them.

And if you (Irina) are after the former, the only way I know how to run two different versions of R *simultaneously* is to have one installed by source (ie. not via the R.pkg which installs into /Library/Frameworks/R.framework) due to the requirement of a valid "Versions/Current" symlink in that R.framework directory. -steve > > On Thu, Jul 29, 2010 at 2:47 PM, Irina Foss <irina.f...@thurso.uhi.ac.uk> > wrote: >> Hello, >> >> I am trying to install two versions of R on a Mac OS laptop to run almost at >> the same time.
