Dear Sirs/Madam,
I am a beginner to R, and I am currently working on a data matrix which looks
like this:
> head(oligo)
ko:K00001 ko:K00003 ko:K00005 ko:K00008 ko:K00009 ko:K00010 ko:K00012
AAA 370 631 365 67 164
455 491
KAA 603 1208 170 157 68
495 922
NAA 60 110 10 7 44
51 94
DAA 183 802 41 62 26
166 263
CAA 58 12 58 1
1 23 8
TAA 451 468 201 90 131
320 518
For certain specific columns, I need to merge the columns in such a way that
the elements get added together.
For example, in order to merge the first and the second columns, my output for
the first row shld be
ko:K00001/ko:K00003
AAA 1001 (i.e. 370+631)
KAA 1811 (i.e. 603+1208)
and so on for the whole column.
A colleague suggested using rowsum, but that seems to add up all the rows for
ALL the columns and not just specified ones. Also, the output doesnt contain
the column or row headers.
Could you please suggest a solution?
Yours sincerely
Nabila Binte Zahur
