1.3 Upgrading Packages

1.3.1 Problem

You want to upgrade a package that is already installed.

1.3.2 Solution

Run update.packages():


It will prompt you for each package that can be upgraded. If you want it to upgrade all packages without asking, use ask = FALSE:

update.packages(ask = FALSE)

1.3.3 Discussion

Over time, package authors will release new versions of packages with bug fixes and new features, and it’s usually a good idea to keep up-to-date. However, keep in mind that occasionally new versions of packages will introduce bugs or have slightly changed behavior.
