Hi, I am having trouble installing R-1.8.1 on my Fedora 1 machine. R is already installed in /usr/local on our network, but I wish to be able to work on my own copy. So I installed it locally using: ./configure --prefix=/scratch/akhan/R-1.8.1 make make install The installation looks fine according to 'make check'. But when I run R I get: Fatal error: unable to open the base package When I echo RHOME using 'R RHOME' I get: /usr/local/lib/R I then tried setting $R_HOME to /scratch/akhan/R-1.8.1, and adding this dir to PATH in my .tcshrc file. Echoing RHOME gives the same response as before: WARNING: ignoring environment value of R_HOME /usr/local/lib/R The 2 copies of R are obviously causing confusion - is there any way of manually overriding RHOME so that I can run R locally? Thanks, Anar
