?contour  in *R* generates the right help page for me.

Can you try following advice in the manual:

   If Emacs reports an error, backtraces can help us debug the problem.
Type "M-x set-variable RET debug-on-error RET t RET".  Then run the
command that causes the error and you should see a *Backtrace* buffer
containing debug information; send us that buffer.

thanks, stephen
