An Introduction to R and RStudio

Updating Packages

There are several ways that this may be achieved:

1. Auto-update in RStudio This is the easiest way to update and maintain your packages. A package update option has been included since version 94.XX, just go to the packages tab and select search for updates. This will open a window and display which (if any) packages have newer versions available. This works for both CRAN and Bioconductor packages.^fn5

2. Via console Bioconductor packages, especially those in the development branch, are updated fairly regularly. To identify packages requiring update, start a new session of R and enter:

   # bioconductor
   source("http://bioconductor.org/biocLite.R")
   old.packages(repos = biocinstallRepos())
   # CRAN packages
   old.packages()
   

To update all installed packages that are out of date enter:

# bioconductor
update.packages(repos = biocinstallRepos(), ask = FALSE, checkBuilt = TRUE)
# CRAN packages
update.packages()

^fn5. This ability appears to change between RStudio releases. As of the current release (0.96.331) it is working. ↩
