# CRAN Mirror

The following guide will allow users to download R packages from CRAN by connecting to a trusted mirror from either a Linux or Windows workstation

In R, issue the following command (change `<package>` to the package you'd like to install):

`install.packages("<package>", repos="http://cran.services.brown.edu")`

You may be prompted with two dialog windows:

`1) Would you like to use a personal library instead?`

`2) Would you like to use a personal library "C:\Users\"....`

Choose **Yes** for both of them.
