I'm running Ubuntu - natty. Forgive me if I sound lost, its been just over a week since I switched over from Windows. I originally installed 2.12 using the Ubuntu software center, but have now switched to using the terminal. 2.9.2 was installed using a .tar.zip file downloaded from cran. Before I switched over to Linux I had both versions installed in Windows, but I had to switch to Linux because Windows is so limiting on RAM use.
Upon further poking around I've figured out how to do it. I found the R executable file in /usr/lib/R-2.9.2/bin, so entering $/usr/lib/R-2.9.2/bin/R starts up version 2.9.2. Thanks for your help. I'm running a CRAN package that has not been updated since 2009, and I'm not rerunning an old analysis. The problem is that the software I'm using for the analysis gives me an error saying that it requires R version 2.4 or higher if I try to run it in version 2.10 or higher. I think someone was a little sloppy with some code so that the program only looks at two integers when verifying the version of R. I've let the author know about it, but the program is no longer in development. -- View this message in context: http://r.789695.n4.nabble.com/running-previous-versions-of-R-tp3670587p3670836.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
