Robert, Happy to help. One quick note, which is that the 2111 version of the kernel was released using that number for FC5, but as 2108 for FC4. This fixes bugs that cropped up in the 2107 version, which I referenced. I did not experience them, but many others did, which seem to be hardware specific to an extent. So you can go ahead and upgrade to 2108 at your leisure. The reason for mentioning the upgrades (not just the kernel, but system wide) is that you never know what other issues may arise from changes/updates in compilers, libraries and applications as bugs are fixed. In addition and certainly non-trivial, are many security patches that have been implemented since FC4 was released in June 2005. One further aside to the thread more generally, is that you might want to look at the R-admin manual relative to some of the pros/cons of updating to 64 bit hardware, since this was referenced in the posts today relative to expanding your RAM limits. It is available online here: http://cran.us.r-project.org/doc/manuals/R-admin.html or as a PDF here: http://cran.us.r-project.org/doc/manuals/R-admin.pdf The URLs above are using a U.S. mirror. Review section 8, "Choosing between 32- and 64-bit builds". There have also been many discussions on 32 vs. 64 bit by folks that you will find in the r-help archives. Using: RSiteSearch("64 bit") will get you almost 900 hits.
