Dear all,

I would like to know how to subset a data.frame by rows.

Example:

   Probesets            34884            34888            34892
1 100009676_at         A                   A                    A
2 10001_at                P                   P                     P
3 10002_at                A                   A                     A
4 10003_at                A                   A                     A
5 100048912_at         P                   A                     A

For this data.frame I want to retrieve only the rows where at least one ´P´ is found. So in this example it would be rows 2 and 5.

Best regards and thanks in advance
