Is there any way to include non-Sweave "vignettes" in packages so that they can be launched with the vignette() function and will show up when doing library(help = packagename)? I'd like to just include a short PDF file with the package which does not come from Sweave sources (just simple LaTeX). Copying the PDF file into the inst/doc directory of the sources, appears to be insufficient. Is this out of the scope of the vignette() function? Thanks, -roger -- Roger D.
