[R] R functions

You'll never figure it out if you don't "play around" with your data.  

Assuming you have been able to import the data, a good place to start is to
look at what tools you have available.    Check out this:
http://cran.r-project.org/doc/contrib/Short-refcard.pdf

check out things like
?which
?max
?unique


You have 2 choices, hope that someone hands you a solution, or fiddle around
until you become proficient.

Good luck.
