Hello,

Your question is not very clear, maybe if you post a data example.
To do so, use ?dput. If your data frame is named 'dat', use the
following.

dput(head(dat, 50))  # paste the output of this in a post


If you want to get the rownames matching a certain pattern, maybe 
something like the following.


idx <- grep("GO:0006355", rownames(dat))
dat[idx, ]


Hope this helps,

Rui Barradas
