I'd like to update MASS from version 7.2-11 to version 7-2.19. I am running R 2.0.1 on ubuntu, that installs MASS with the package r-cran-vr.
First, MASS is part of VR, so it is VR you update.
Thanks Prof Ripley, and Kjetil too, for your help. I am sure this was obvious to anyone but me, but I found the wording in http://www.stats.ox.ac.uk/pub/MASS4/Software.html#RUnix a bit confusing. May I suggest that where it says ``To get the very latest version, use update.packages() from an R session'', it could be added: ``Note also that the current version of your R base system may limit the update, i.e. if the R base system you are running is too old, you will not be able to get the latest version of MASS. You can check the dependencies of MASS from the <a href="http://cran.r-project.org/src/contrib/Descriptions/VR.html">Description file of VR at CRAN</a>''. And maybe right before ``As the VR bundle is now recommended'' it could say ``MASS does not have its own package, but comes bundled with other libraries in a package called VR. Thus if you want to use/update MASS you need to install/update VR''.
Your R is seriously only of date. You might want to wait a week and then install 2.2.0.
Searching a bit more I have found that this problem has been brought up in the ubuntu forums http://ubuntuforums.org/archive/index.php/t-49178.html i.e. that the GNU R version is too old. As a temporal fix, it is suggested to install the sarge .deb packages from http://cran.r-project.org/ and then Linux/debian/stable, overlooking the dependencies error with libc6. I'll update to 2.2.0 in a week, but for the moment I did the former and it seems to work with the code I was writting. Cheers,
