Please first read "An Introduction to R" (one of the pdf manuals that
ships
with R) before posting these sorts of questions, as it is written
specifically to help you get started (I think fairly clearly).
Other (links to) learning resources may be found on the CRAN website. Please
take advantage of them. One that you may find particularly helpful is:
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.
Yes, the initial learning curve is steep. However, if you do any serious
data analysis and/or plotting, I promise that you will find it well worth
your while.
