Thank you Richard, but I dismissed the 'ifelse' solution because it
needs explicit manual definition of the factor levels and corresponding
vectors' combinations and does not define it automaticaly from the
'cas' data-frame (from which values, number of levels and rownames can
vary).

1) Traffic at the r-help list should be kept at a reasonable level lest
it becomes completely unmanageable and un-r-helpful.
2) People will continue to misread, overlook or disregard the manuals
and come up with questions that many others will consider silly.

Hi!
Sorry for asking a trivial questions, but I can't seem to figure this out.
I have a dataframe called master containing 30-odd variables.
In this dataframe, I have observations across these 30 variables from
1930 to 2003 (I've made a year variable). How can I drop all rows for

Yup.
The best idea I can come up with is that you might have a dud
install command sitting somewhere and getting in the way. I believe
this has tripped IRIX users before, but I could be wrong.
You seem to

Thanks.
The problem is that there is extremely little on dataframes or matrices
in An Intro to R, which I did read and I frankly don't know where else
to go.
Once I know a function like subset() exists, I can then read the help
files on it and that's fine, but I would never dream this function

Much of R-intro was written as an introduction to S before R existed and
later translated, so there are quite a few things that aren't in it but
