That's a good suggestion and one that I discussed several times with
Kurt. The problem is that citation() only looks at the installed
package which doesn't know where it came from. Thus, I have AFAIK no
simple means of checking whether a particular package I'm using was
obtained from CRAN, Bioc, R-Forge, or some local source package.
Hence, the URL cannot be included automatically.
Right -- hence patching citation() is not a general answer.
I agree that this would be nice to have. One idea would be that the
CRAN maintainer adds a line to the DESCRIPTION file upon release to
CRAN. There are a few ideas how to do this exactly and it's not yet
implemented.
Well, one solution might be for the build script that runs on CRAN to
add a URL line to the DESCRIPTION file
(if one is not already present), in the same way it adds other lines
