Hi, The daily build report showed a similar error in several of my packages when building on Linux and Windows. I was able to reproduce this error under R-devel on Windows and it pops up when using the citation() function. In particular with BiocParallel and S4Vectors.
This error doesn't pop up in the build report for BiocParallel or S4Vectors and I believe that's because they are not using the citation() function in their vignettes. However, I would have guessed that this error would affect the Bioc-devel landing pages but it hasn't. I haven't found any leads when looking at the DESCRIPTION files for these packages (they don't have a inst/CITATION file). So my guess is that this is really a bug in citation() for R-devel. If anyone has a guess please let me know. I didn't see a thread about this in R-devel (last 3 months) so I'll likely re-post this there if needed.
