Apparently also a possibility, I guess it can be made to work with
the original example and my extensions.
  

i guess it does work with the original example and your extensions.

And I thought that you would have known for sure.....

Though, it seems to require the knowledge of perl, or at least
perl's regular expression.    

oh my, sorry.  it' so bad to go an inch out of the cosy world of r. 

Well, if that's how you feel, don't do it.

I regularly use other languages besides R.  Mostly C and Fortran,
occasionally Python.  But I never found time to learn Perl or Java or
awk or C++ or....; some people do not have the time to learn all
languages under the sun. Also, if one concentrates on a few, one can
learn them really well.

but, as gabor pointed, 'perl=TRUE' is inessential here,

I thought that your answer to Gabor indicated that, depending on the
context, perl=TRUE was essential; though I must admit that I did not
run that code.

so you actually need to know just (very basic) regular expressions,
with no 'perl' implied.  having learnt this simple regex syntax you
can avoid the need for looking up strsplit and paste in tfm, so i'd
consider it worthwhile.

As people say, YMMV, I do not need to look up strsplit and/or paste;
but I would have to look up what the regular expression syntax or
finally memorise it; something I did not consider worthwhile so far.
