No quibble with the advice, but it prompted me to look again at the R Intro.
Interestingly, the Intro doesn't mention subset() at all; the subsetting
operations referred to there are all based on indexing (mostly because that
section is intended to be about indexing, of course).
Subsetting using subset() is perhaps the most natural way of subsetting data
frames; perhaps a line or two and an example could usefully be included in the
'Working with data frames' section of the R Intro?
