Updates to R packages rarely time up with our terms, often requiring updates to either R or other packages in the middle of the semester causing lost time in the classroom.  Each term we will update this page to include a repository you and your students can use to keep your packages consistent throughout the term. We will ensure the repository is compatible with the version of R and R-Studio installed in all virtual and physical labs. The instructions below include how to point R-Studio to our 'Semester Locked Repository', getting the latest packages from the SU Package Manager, as well as getting the latest packages from CRAN.
