*do* have a look at e.g.:

- http://www.ms.unimelb.edu.au/~andrewpr/r-users/icebreakeR.pdf 
(contributed manual)
- http://cran.r-project.org/doc/contrib/Short-refcard.pdf  (reference-card)

to search the archives you can use:

yes

source( "yourScript.R" )

check working path: getwd()
if you don't know what this is:
  ?getwd
