Something like:

if (!require(pkg)){

        install.packages(pkg)
}

Subject: [R] Install package automatically if not there?

Hi fans,

is it possible for a script to check if a library has been installed? I want to automatically install it if it is missing to avoid scripts to crash when running on a new machine...
