R help - May 2011 - UNIX-like "cut" command in R

The R "cut" command is entirely different from the UNIX
"cut" command.
The latter retains selected fields in a line of text.  I can do that kind 
of manipulation using sub() or gsub(), but it is tedious.  I assume there 
is an R function that will do this, but I don't know its name.  Can you 
tell me?

I'm also guessing that there is a web page somewhere that will tell me how 
to do a lot of common GNU/UNIX/Linux "text util" commmand-line kinds
of
things in R.  By that I mean by using R functions, not by making system 
calls.  Does anyone know of such a web page?

Thanks in advance.

Mike
