comparing columns and printing overlapping rows

Hi All,

I have two files.
1. with only one column
2. data matrix

I need to compare first columns of both files and print the rows from
second file for the overlapping entries. I have solutions for awk and sed,
but I need how to do it in R.
Thanks

Regards
Anchal
