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?

Try subd <- d[, "gene" ==
c("i1","i2","i3")]

Hi Anjan,
Try
subset(d, gene %in% c("i1", "i2", "i3"))
HTH,
