OK - so I followed the following steps, which I think rule out those causes
1) I uninstalled all remaining versions of R, and then deleted all the directories in c:\progra~1\R 2) I restarted the computer 3) I installed 2.14.2, and attempted to install the Rcmdr package. Same error message for both the cars package and the Rcmdr package. 4) I then exited and confirmed that I have write permission to C:\progra~1\R\R-2.14.2\libraries both by looking at the permissions, and by creating a directory in there. I appear to have full control, and I could create the directory. note that R is able to create the temporary directory to install the package, but not the correct, final directory. 5) I then uninstalled 2.14.2, and installed 2.15.0, hoping for a fix. No luck. Same error message. 6) I then tried installing the packages to a different directory, one that I created, c:\test, using install.packages("Rcmdr","c:\\test") This time, the car package installed correctly, but Rcmdr still had the same warning message Warning: unable to move temporary installation c:\test\file136c67c337b3\Rcmdr to c:\test\Rcmdr There is clearly something messed up on this computer, but I'm at a loss for how to get around it. Thanks for the suggestions, and I guess I have to work on a different computer! 2012/3/31 Uwe Ligges <lig...@statistik.tu-dortmund.de> > On 31.03.2012 16:15, Drew Tyre wrote: > >> Hi all, >> >> I'm having a strange error that prevents me from installing new packages, >> or updating packages after reinstalling.
