For the CRAN add on packages (which includes the 'recommended'
packages), each has the license information under the description. For
example, MASS which is part of the VR bundle, is here:

http://cran.r-project.org/src/contrib/PACKAGES.html#VR

The information is as follows:

...
License: GPL (version 2 or later)
...

Some of the packages are released under other licenses or have
restrictions on commercial use or distribution. Read each one carefully.

HTH,
