Hi all:

Happy summer solstice to all northern hemispherics (and winter solstice to the southerners).  

Newbies (and others!) may find useful the R Reference Card made available by Tom Short and Rpad at http://www.rpad.org/Rpad/Rpad-refcard.pdf or through 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 session packages** for functions using rexexp'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 usually be found this way.
