[R] Using "R" to find peaks in sampled data

This is probably a trivial question, but I did
not see it in the FAQs.  Perhaps I simply need
to be pointed to some URLs.

In any case, I have some sampled data that has peaks,
and I would like to extract peak height, location, and
width, according to almost any statistical model.
Gaussian would seem to make the most sense.

There can also be "steps" increasing the amplitude
over a region, that should also be captured and removed
before the peak analysis.

Can anyone point me to either some FAQs, or "R" code
to do this?  I have not yet installed "R", and this
is the only current use I would have for it and I want
to know if it makes sense to bother before going to
the effort.
