How can I extract the samples (S1-S5) containing a TRUE value in their row?
Solution should apply to a much bigger data frame.
> a
Samples A B C D . . .
1 S1 FALSE FALSE FALSE FALSE
2 S2 FALSE FALSE NA TRUE
3 S3 FALSE FALSE FALSE FALSE
4 S4 FALSE TRUE FALSE FALSE
5 S5 FALSE FALSE FALSE FALSE
.
.
.
Thank you guys, I appreciate your help a lot!
