Some useful resources include the following:

At the R console, ?functionname (for example, ?help) brings up help materials and use of ??help will bring up a list of potentially relevant functions from installed packages.

Subscribing to and asking questions on the R-help mailing list at r-project.org/mail.html allows you to communicate with some of the leading figures in the R community as well as many other talented enthusiasts. Do read the posting guide and research your question before you ask any questions because it's a busy and sometimes unforgiving list.
