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
