Hello all R users, I have a problems transforming (or maybe better regrouping) a data.frame. I have a big data.frame, which I would like to sum up according to a specific column.
This is an example of my matrix: ID gen 0042787 gen2 0016070 gen2 0016070 gen3 0007409 Gen1 0007409 gen3 0006511 gen2 0006417 gen3 0016070 gen4 0006511 gen4 I want to rearrange the matrix according to column GO, so that it will look likes that: GO:0042787 gen2 GO:0016070 gen2 : gen3 : gen4 GO:0007409 gen1 : gen3 GO:0006511 gen2 : gen4 GO:0006417 gen3 I've tried it with the package doBy (lapplyBy and paste) but it just doesn't work out. I will be very happy for any suggestions you might have to help me. Thanks Assa [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
