R help - Mar 2009 - Characters To Matrix

Hi,
   I have a data set that I read in using readLines, but R classes it as a
character string. The data set has multiple columns and rows, but I only want
the first 2 columns in the form of a matrix. Thanks for the help.

Why aren't you using 'read.table'?
