Symbol size in plots

Dear R-listers,
what is the best way to draw an XY scatterplot with symbol size 
proportional to the value taken on by a third variable?
Thank you very much for any help,
Maurizio Pisati

A mild suggestion, by the way, is that "circle", "star", etc. be added
to the _keywords_ of symbols().  It took me a while to find it in the help
the last time I was looking for it.

  What are the possibilities that a _full-text_ search capability could be
added to the help front-end?  Would it be prohibitively slow?  (Or is
there adaptable software that would, e.g., index all words except a list
of stopwords into a reference database?)

well, not "\keyword{.}" which must be from among a pretty small set.

However,  help.search("circle")  would find  `symbols()' if

- the \description{.} would be in the data base
- the default fields of help.search(.) would contain "description"
  (and they *should* really contain "alias" when they contain "name"
   in my opinion!).

Not only would it be quite slow and the database quite large,
I think you'd get quite a lot of false matches
[Well that could be taken care of when one would use a dialoguing frontend..]

I did have that same (for a full text search) wish myself..
Martin

However, I think that the database should start containing \description{.}..
