[R] Failure loading library into second R 2.3.1 session on Windows XP
Hi. I am using R 2.3.1 on Windows XP. I had installed a library package into my first session and wanted the same package in my second session, so I went out to the CRAN mirror and tried to install the package, and got the following message: *********************************************************************>utils:::menuInstallPkgs()trying URL 'http://cran.ssds.ucdavis.edu/bin/windows/contrib/2.3/corpcor_1.4.4.zip' Content type 'application/zip' length 133068 bytes opened URL downloaded 129Kb package 'corpcor' successfully unpacked and MD5 sums checked Warning: cannot remove prior installation of package 'corpcor' The downloaded packages are in C:\Documents and Settings\Talbot\Local Settings\Temp\RtmplCxarb\downloaded_packages updating HTML package descriptions>library(corpcor)Error in library(corpcor) : there is no package called 'corpcor' ********************************************************************* After rebooting my machine, I dug into this a little further. Upon installing a package from a CRAN mirror, it seems to stay on my hard drive, and I can load it in subsequent sessions from the "Load package..." menu without going back to get it from a CRAN mirror. However, if I do happen to retrieve it again from a CRAN mirror, it appears that may corrupt the version that was saved, and it no longer will be available from the "Load package..." menu. A reboot and re-retrieval of the package makes it available again; I don't know whether there's any less drastic solution. This behavior doesn't occur with every package, but I have experienced it with two different packages (corpcor and copula), so there seems to be something going on. I didn't see anything in the FAQ page about this, I wonder if anyone can tell me more about this issue. Thanks! -- TMK -- 212-460-5430 home 917-656-5351 cell

You can only expect that update / reinstall a ***package*** works if you have not yet loaded it into your R session. Hence close R, start it without loading the relevant package and then update/reinstall. Best, Uwe Ligges Talbot Katz wrote:> Hi. > > I am using R 2.3.1 on Windows XP.
