How to view package license file?

Question

I have a package called my_pkg and in my DESCRIPTION file I've declared my license as License: file LICENSE.

Another question suggested using packageDescription to call the license, but that yields the following:

> packageDescription('my_pkg', fields = 'License')
"file LICENSE"

Any ideas how to proceed? I've checked CRAN and Hadley's R Packages book to no avail.

Answer 1

I think

file.show(system.file("LICENSE",package="my_pkg"))

should work (it works for the ggalt package). It won't work if there is no LICENSE file, of course ...
