Hello,
I would like have an automatic way to avoid installing packages that I cannot
use due to license restrictions.
For example, the conf.design package is limited to non-commercial use, and
since I work for a for-profit business, I cannot use it.
I found out about the license terms of conf.design by chance; I would like to
avoid any possibility of a mistake in the future.
Is there some clever combination of grep and install.packages that I could use
to limit my downloads to, say, GPL-only packages?
In theory, you should be able to look at the License field of
available.packages(fields="License") and limit yourself to those with
acceptable licenses. However, I don't think CRAN reports on the license.
However, after you have installed a set of packages, you can scan the
set of licenses using this code:
installed.packages(fields="License")[,"License"]
