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
