Question: This looks awfully clumsy; is there some more idiomatic way
to do this, in particular to refer to the match.length attribute
without using a quoted string or the attr function?
attributes(matches[[1]])$match.length and
attributes(matches[[1]])[[1]] work, but seem even clumsier.
Question: R uses names like xxx.yyy in many places. Is this just a
convention to represent spaces (the way most languages use "_"), or is
there some semantics attached to "."?
Question: Is it good practice in R to treat a string as a vector of
characters so that R's powe...

R as a non-functional language
I'm reading Torgo (2010) *Data Mining with
R*<http://www.liaad.up.pt/~ltorgo/DataMiningWithR/code.html>in

that is very non-functional.
> pH <- c(4.5,7,7.3,8.2,6.3)
> names(pH) <- c('area1','area2','mud','dam','middle')

run faster?
HOSTS=()
for host in $(grep -h -o "[-\.0-9a-z][-\.0-9a-z]*.com" ${TMPDIR}/* |
sort | uniq); do
HOSTS+=("$host")
done
