All,
Is there are a wildcard in R for varible names as in unix? For example,
rm(results*)
to remove all variable or function names that begin w/ results?
cheers,
Dave

rm() can take a list of object names as an argument and ls(pattern='^results')
gives such a list. So
rm(ls(pattern='^results'))
would remove all objects that are matched by the regular expression, that is all
that begin with 'results'

In R 2.2.0, there is the function 'glob2rx()' which can be used for this
purpose. As in
rm(list = ls(pattern = glob2rx(results*)))
