Hi there
I 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 ?/home/xx/R/x86_64-pc-linux-gnu-library/2.13?
(as ?lib? 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.
