Greg,
I am assuming that your data is in a text file. R is a good tool but not
the tool I would use for this job. The tool I would
use is grep. The following command should get you want you want:
grep -v "^rs" <data file name>

Hi all;
I have a file which has about 3.000.000 lines. Most of the lines at first
column start with "rs", for example, rs10000056, rs10000076 and so on. I
would like to get the lines which do not start with "rs" . Your helps
highly appreciated.
Regards,
Greg
