Hi all: 

Newbies (and others!) may find useful the R Reference Card made available by

Tom Short of EPRI Solutions at http://www.rpad.org/Rpad/Rpad-refcard.pdf  or
the "Contributed" link on CRAN (where some other reference cards are also 
linked). It categorizes and organizes a bunch of R's basic, most used 
functions so that they can be easily found. For example, paste() is under 
the "Strings" heading and expand.grid() is under "Data Creation." For 
newbies struggling to find the right R function as well as veterans who 
can't quite remember the function name, it's very handy. 

Also don't forget R's other Help facilties: 

help.search("keyword or phrase") to search the **installed** man pages 

RSiteSearch("keyword or phrase") to search the CRAN website via Jonathan
Baron's search engine. This can also be done directly from CRAN by following
the "search" link there.

And, occasionally, find()/apropos() to search the ** attached** packages for
functions using regexp's. 

Though R certainly can be intimidating, please **do** try these measures
first before posting questions to the list. And please **do** read the other
basic R reference materials. Better and faster answers can often be found
this way.
