Please, I am having problems in the process of installing the R-packages in the R_HOME/library. The following message is the error that I am getting: # R CMD INSTALL -l /usr/local/bin/R/library base WARNING: package 'base' does not exist ERROR: no packages specified # R CMD INSTALL -l /usr/local/bin/R/library tools grep: tools/DESCRIPTION: No such file or directory ERROR: cannot write to or create directory '/usr/local/bin/R/library' Because I am new to the Linux environment, this problem seems unresolvable for me. I have searched the internet for solutions and this is what I have tried: # ln -s /usr/bin/perl /usr/local/bin/perl # R CMD INSTALL -l /usr/local/bin/R/library base WARNING: package 'base' does not exist ERROR: no packages specified But, it does not work and I don't even know if it is related. Please, I need answer quickly as it is needed for my school projects. Olatunde
