Dear R-sians
Quick question...

1) From a flat (data) file with 100+ columns, how do I read specific columns
instead of reading the entire dataset? I am trying to avoid reading the
entire file followed by "subsetting".

2) is the a way to a call a column of dataframe through a variable.. e.g.

e,g
var="date"

something like...
data${var} <- "02 Oct 2009?

santosh
