Hello list,
I have a data frame M like:
BAC chr pos s1 s2
RP11-80G24 1 77465510 -1 0
RP11-198H14 1 78696291 -1 0
RP11-267M21 1 79681704 -1 0
RP11-89A19 1 80950808 -1 0
RP11-6B16 1 82255496 -1 0
RP11-210E16 1 228801510 0 -1
RP11-155C15 1 230957584 0 -1
RP11-210F8 1 237932418 0 -1
RP11-263L17 2 65724492 0 1
RP11-340F16 2 65879898 0 1
RP11-68A1 2 67718674 0 0
RP11-474G23 2 68318411 0 0
RP11-218N6 2 68454651 0 0
CTD-2003M22 2 68567494 0 0
.....
how to remove those rows which have 0 for both of columns s1,s2?
sth like M[!M$21=0&!M$s2=0]?
Moreover, I want to get a list which could find a subset of rows which have
the same pattern of data. For example, the first 8 rows in M can be
clustered
into 2 groups (represented below in 2 rows) and shown as:
chr Start End # of rows Pattern
1 77465510 82255496 5 (-1 0)
1 228801510 237932418 3 (0 -1)
Can anybody help me out of this? Thank you very much and happy holiday!
Best,
Allen
