Hi, I have two vectors *res* and *x* res[,1][1:5] [1] GO:0003910 GO:0003980 GO:0004289 GO:0004422 GO:0005085 15 Levels: GO:0000010 GO:0000014 GO:0000033 GO:0000036 ... GO:0080025 > x[,1][1:5] [1] GO:0070060 GO:0051083 GO:0042351 GO:0006189 GO:0051084 100 Levels: GO:0000001 GO:0000002 GO:0000003 GO:0000005 ... GO:0080142 res is the subset of x I want to find the index of res elements in x Any suggestions?

Hi ALoK, couldn't you use something like: sapply(res[,1][1:5],function(y){grep(y,x[,1]) }) Cheers, Artur On Fri, Oct 9, 2009 at 4:08 PM, ALok <foralok@gmail.com> wrote: > Hi, > I have two vectors *res* and *x* > > res[,1][1:5] > [1] GO:0003910 GO:0003980 GO:0004289 GO:0004422 GO:0005085 > 15 Levels: GO:0000010 GO:0000014 GO:0000033 GO:0000036 ...
