Oh, please use a released version or 2.0.0 alpha.

I don't think this is correct about \author.

Outside *verbatim* environments.

Inside the first argument of \eqn and \deqn only.

They are not.  They *are* generated by R CMD check, as that checks the 
latex help files.  If you want a .ps manual for a package use R CMD RD2dvi
and then run the appropriate dvi-to-ps command on your system (R does not 
know about such commands).
