Hi Eduardo

I have just realized that I did not my send previous message to r-help

You do not need to put it in a float but you must 
create the graph in a chunk, all you need is the \includegraphic command
This may avoid float space problems and make it easier for many graphs.
with the appropriate reference labels or 
bookmarks using pdfbookmark or with with the \usepackage{zref}
(I have only looked at it - I need a very full 
quick start guide for it as my requirements are complicated.)

If you get Sweave to do it automaticaly it puts it in a float
