Hello, I have run across the following problem: Creating PDF files manually by using pdf(version='1.4') I can make graphs using the new transparency feature of R2.0. If, however, I try to create the same graphs with Sweave, all transparent stuff is gone. This os likely due to the default version parameter in in pdf(). How can I tell Sweave to use the newer PDF version? The parameter seems to be hard-coded (not via some option) and I could not come up with some kind of hook ... Thank you Benno PS: Sorry for re-posting, yesterday I seem to have relied to another posting which may have buried mine in some readers
