Additional add-ins / libraries can be added to R-project and R-Studio by running the following script when you first start using R. Then as you add your libraries and add-ins they will be added to your ITaP "W" drive that will follow you and be available on all campus computers. Anytime you use a version of R, simply run this script and then you will have the add-ins / libraries that you need.
my.dir <- "W:/My Documents/Rlibs"
if (!file.exists(my.dir)) dir.create(my.dir)
.libPaths(c(my.dir, .libPaths()))
.libPaths()
