Please provide the code you used to attempt this, as well as the error
you get when you attempted it ("it doesn't work" is not very
informative), as well as the output of `sessionInfo()` so that we know
what package versions (plus system architecture) you are running.

Please try searching the list archives for previous recommendations
for solutions to this problem, as it is discussed quite often. Perhaps
most recently here:
