Thanks for the comments. I had got Thomas' message wrong the first time. Now, I have downloaded and re-installed the latest version of R. After reading the "administration and maintenance" manual, I added
deb http://cran.R-project.org/bin/linux/ubuntu dapper/ to my sources.list file and used apt-get to install the latest version. After the installation, I used update.packages() from with R to update all the packages. Let me know if this was what was required or I made some mistake. I have two questions: 1. When a new version of R is released (every 6 months or so I believe) will I have to uninstall the version of R in my machine and then download and install the latest version? 2. When I used update.packages() from within R (after installing the latest version), I still got the following warning messages: Warning messages: 1: installation of package 'cluster' had non-zero exit status in: install.packages(update[, "Package"], instlib, contriburl = contriburl, 2: installation of package 'mgcv' had non-zero exit status in: install.packages(update[, "Package"], instlib, contriburl = contriburl, 3: cannot create HTML package index in: tools:::unix.packages.html(.Library) I cannot understand what to make of these? Thanks for all the help.
