Documentation says (emphasis mine): "Registers an R function to be called upon garbage collection of object OR (optionally) at the end of an R session." Should this say "and" and not "or"? THK -- http://www.keittlab.org/ [[alternative HTML version...

I bumped a package to CXX14/17 and it failed on Travis/Appveyor while checking fine locally. I assume I need to request different compilers or something like that. Anyone have a quick recipe for that? THK [[alternative HTML version...
