Sweave and multipage lattice

Dear R-Listeners,

as the Sweave faq says:

http://www.ci.tuwien.ac.at/~leisch/Sweave/FAQ.html

creating several figures from one figure chunk does not work, and for
standard graphics, a workaround is given. Now I have a multipage trellis
plot with an a-priori unknown number of pages, and I don't see an elegant
way of dividing it up into multiple pdf-files.

I noted there is a "page" event handler in the ... parameters, which would
provide a handle to open/close the file.

Any good idea would be appreciated.

Dieter
