Yes, Paul, definitely it helps. Thanks!

I obtained what I wanted. 

Now, I want to control the output of the pdf() command making it write
a specific file chosen by me and not the system. After reading the
help page for the pdf, I was unable to do it.

E.g. I issued
 
onefile<-FALSE
pdf(file=ifelse(onefile,,"vic.pdf")
example(layout)


And I obtained a 5-pages vic.pdf with page 1-4 full of "nasty
rectangles" of any kind and page 5 with the right picture.

Please help
