I think you want to take a look at "An introduction to R", page 76 in
particular. It is usually installed along with R itself, otherwise
take a look at

http://cran.r-project.org/doc/manuals/R-intro.pdf

(Requires Acrobat reader or similar software. The introduction is also
there in HTML format, but without pictures, and the one on p.76 is
fairly crucial to your issue.)
