Beware that .Rhistory file has not unlimited number of commands, you 
can see only about 500 lines in default setting, however you can 
modify it.

Beware of mouse elbow when perusing mouse too much.
If you want interactive help just open HTML help pages with your 
favourite browser.


PS. It is good to have a copy of Paul Johnson's Rtips somewhere near 
when you start. Basic stuff and howtodo's is covered there.
