codewhere - Find the Location of an R Package's Code
Find the location of the code for an R package based on
the package's name or string representation. Checks on CRAN
based on information in the URL field or BioConductor and
GitHub based on constructing a URL, and verifies all paths via
testing for a successful response. This can be useful when
automating static code analysis based on a list of package
names, and similar tasks.
