[R] reading in a subset of a large data set

I have a huge dataset for which I only want to read in a subset of it. Is it possible to use read.table to read in only a subset of the data? For example, something like read.table('~/data.txt', subset = chromosome=='1' )

If not, then why not? This seems to be a feature available in all other statistical software.

Thanks,
Stacey
