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 [[alternative HTML version deleted]]
