Jeff, Sorry for the delay, but your email appeared in my mailbox today (Sept 1). This is a 64bit issue, which may or may not be unique to Ubuntu (I have never used an other 64bit distro). It turns out that /usr/lib64 is directory that links to /usr/lib, so R thinks all of the directories are installed twice, but there is only one version on your machine. Why there are two directories, I don't know. My guess is that some code looks in /usr/lib64, other in /usr/lib knowing it is a 64bit system. It is annoying on the R end of things, but necessary for the system. Hope this helps, Michael

I am new to ubuntu, but have used R for years on Fedora. I have a simple question that I do not quite understand. I first installed R from the ubuntu repository (2.6.2 I believe it was--whatever is current there) before finding the debian/ubuntu SIG here when searching for R 2.7.1. Subsequently I upgraded to 2.7.1 using the instructions at http://cran.r-project.org/bin/linux/ubuntu/. I am using Hardy on an amd64 platform. I did both installations with synaptic. The question I have is why I end up with what appears to be two installation of R? I first noticed this when I looked at the package list and there were two sets of documentation for all of the packages; i.e., in /usr/lib/R/library and /usr/lib64/R/library. Checking these directories on disk shows what appears to be full mirror installations. In addition, running the little script to check for multiple packages at the R wiki for debian returns... Warning: you have multiple copies of the following packages: Package LibPath Version base "base" "/usr/lib/R/library" "2.7.1" base "base" "/usr/lib64/R/library" "2.7.1" boot "boot" "/usr/lib/R/library" "1.2-33" boot "boot" "/usr/lib64/R/library" "1.2-33" ... etc. At first I thought that synaptic had left the earlier version on, but this obviously shows that there are two sets of the same packages. This does not happen on my fedora 64 installation. Also, FWIW... R.version _ platform x86_64-pc-linux-gnu arch x86_64 os linux-gnu system x86_64, linux-gnu status major 2 minor 7.1 year 2008 month 06 day 23 svn rev 45970 language R version.string R version 2.7.1 (2008-06-23) Any thoughts? Many thanks, sorry for such a simple question. I admit to being on the learning curve for unbuntu, and am more used to fedora/yum for installations. Sincerely, Jeff Gove
