No problem. Actually, I missed a comma. You should do A[,seq(1,dim(A)[2],2)] Julian affy snp wrote: > Hi Julian, > > Thanks for the help! > > Best, > Allen > > > > On Nov 9, 2007 11:08 PM, Julian Burgos <[EMAIL PROTECTED]> wrote: > >> There are many ways. For example, you can do some

There are many ways. For example, you can do something like A[seq(1,dim(A)[2],2)] Julian Julian M. Burgos Fisheries Acoustics Research Lab School of Aquatic and Fishery Science University of Washington 1122 NE Boat Street Seattle, WA 98105 Phone: 206-221-6864 affy snp wrote: > Dear List

[R] How to subset a portion of columns from a matrix
