[R-pkg-devel] error in windows R-devel builder, but not anywhere else

[Duncan Murdoch]

Looks like this recent change to R-devel has caught you:

       \code{is.atomic(NULL)} now returns \code{FALSE}, as \code{NULL}
       is not an atomic vector.  Strict back-compatibility would
       replace \code{is.atomic(foo)} by \code{(is.null(foo) || 
is.atomic(foo))}
       but should happen only sparingly.

I don't know why you didn't see this on the other platforms; maybe they 
just haven't been rebuilt recently.

Rcmd checks also finds no issues on GitHub (I use rather strict Rcmdcheck workflows on GitHub, so any issues should be found quickly on GitHub; see https://github.com/tony-aw/tinycodet). But on the Win R-devel builder, I get an error. I use a Windows computer myself, and I can see where the error takes place on the win R-devel-builder, but I cannot reproduce the error. The error should not even be there.

This is also the error message that occurs in Win R-devel Builder, but it shouldn't be there, since no incorrect string is specified for "rt" there - otherwise, all operating systems would give an error there.
