Details of *what* didn't work would be helpful, like for example
error messages.
Regardless, I'd do it like this:
subd <- d[, d$gene %in% c("i1","i2","i3"), ]
d
gene 1 2 3 1 i1 1 6 11 2 i5 2 7 12 3 i2 3 8 13 4 i3 4 9 14 5 i1 5 10 15
d[d$gene %in% c("i1","i2","i3"), ]
gene 1 2 3 1 i1 1 6 11 3 i2 3 8 13 4 i3 4 9 14 5 i1 5 10 15 Sarah On Wed, Dec 29, 2010 at 5:29 PM, ANJAN PURKAYASTHA

Hi, I'm having a problem with a step that should be pretty simple. I have a dataframe, d, ?with column names : gene s1 s2 s3. The column "gene" stores an Id; the rest of the columns store intensity data. I would like to extract the rows for gene Ids i1, i2, i3 ( I know a priori that those rows exist). So I do this: subset(d, gene %in% c(i1, i2, i3)). This does not give me the required data. Any ideas where I am going wrong? TIA, Anjan
