Hello dear R-list!
I have an alphanumeric matrix (mymat) like this one:
(Embedded image moved to file: pic06334.pcx)
with 13000 rows (5 columns), I want to extract from it a submatrix following a
citeria:
col(5)<0.01.
I tried with :
> sub.mymat <- mymat[as.numeric(mymat[,5])<0.01,] #
"as.numeric " because elements are quoted!
but this give a bad result (I filtered mymat with two different spreadsheet
obtaining a result
very diffrent from that obtained with previous R-line).
Some suggestion?
Thanks in advance!
A.S.
