Upgrading R

Several times a year, new releases of R become available from CRAN. The following steps are recommended to minimize the possibility of problems when upgrading to a new R release to use with the R Integration Pack.

If an R 3.x installation is not available here for your version of Linux, third-party tools such as the Yellowdog Updated, Modified (Yum) and Extra Packages for Enterprise Linux (EPEL) can be used to install and update your R installation.

To Upgrade your R Environment

1. Uninstall the old version of R. Uninstalling R removes files from the initial installation, but not packages that have been installed or updated.

   See the third-party R documentation for steps to uninstall R for your machine configuration.

2. Install the new version of R from CRAN.
3. Copy any installed packages from the old installation library folder to the new installation library folder.

4. In a new R console, run the following command:

   Copy

   update.packages(checkBuilt=TRUE, ask=FALSE) 

5. Delete any files left from the old installation.
