Where to report bugs of R packages?

Question

Some packages do have a reference to bug reporting system, others do not. Where should I report package bugs then? Is there any default bug reporting system for packages which don't have their own?

I found https://bugs.r-project.org/bugzilla3/ but when I look at the components it seems more like for the R core. I also tried bug.report(package = "runjags"), but it tried to start mail program which is not very useful.

Answer 1

If in doubt, send an email to the package maintainer.

packageDescription("thepackagename", fields = "Maintainer")

(This is what bug.report does.)
