Actually how you built the .pdf is irrelevant, but it does look for file with the same name and one of these extensions: "Rnw" "rnw" "Snw" "snw" "Rtex" "rtex" "Stex" "stex" So you could just create a zero length file with the same basename and one of those extensions, and it should work. I don't know if this restriction is intentional. Duncan Murdoch > > Prof Brian Ripley wrote: > >> This looks very like the print method for vignettes.
