[R] how to keep up with R?

I agree! The best way to learn (and remember for longer) is to teach 
someone else about it.

And there is not reason not to repeat some of the anlysis done on SAS 
with R. That way you can verify your outputs or compare the 
presentations. If you consistently find differences in the outputs, then 
trying to figure out the reason may lead you to better understand the 
methods (e.g. different optimization or estimation procedures).
