We recently upgraded our WeBWorK server and now have R integration. This is great news, but I can't find any documentation that tells me how to use R packages (or that it isn't possible). Using R without any packages is very limiting, so I'd like to be able to this.
Even if packages cannot be loaded inside a problem, I'd settle for being able to include the packages I want in some sort of server configuration. (But this makes the problems less portable. It would be better if the problem indicated which packages were required for the problem to work.)
Does anyone know how to work with R packages in WeBWorK?
