Hi thereI have an Rscript and I am looking for a way to install a package non-interactively. In Rscript {Utils}, I saw an example which does something like this, however this does not seem to work for my particular example. I am trying to install the following package in an Rscript (without switching to interactive mode). res <- try(install.packages("DEoptim")) if(inherits(res, "try-error")) q(status=1) else q() Error: Installing package(s) into β/home/xx/R/x86_64-pc-linux-gnu-library/2.13β (as βlibβ is unspecified) Error in contrib.url(repos, type) : trying to use CRAN without setting a mirror Any idea how I can fix this or specify "lib"? Any help would be most appreciated.
You need to set a CRAN mirror. options("repos") should not contain the dummy value "@CRAN@", you should put in the URL of your mirror.
