[Bioc-devel] R CMD check WARNING file link 'x' in package 'y' does not exist and so has been treated as a topic

[Benjamin Tremblay]

Hi,

I’ve actually had the exact same problem. The solution for me was to change \link[pkg:foo]{bar} where foo is the actual .Rd filename in the original package. Downloading the limma source reveals there is an Rd file named 01Introduction.Rd, without the dot as you had it. So it would look like:

\link[limma:01Introduction]{limma}

Hopefully this works for you.

I hope this WARNING will not prevent piano from being included in the next release, as it is “only” a documentation issue?
