Dear Michael,

I know this situation from writing vignettes and I usually cheat a bit

I redefine the functions along these lines:

plotmap <- function (...) print (hyperSpec:::plotmap (...))

   (plotmap is a lattice-function for hyperSpec objects)

plotmap can tehn be used without the print in the vignettes - this works fine for almost all cases. Only, if you have a structure that one of the redefined functions call another one of them, you get e.g. a pdf with 2 pages.

Have a look at the vignettes and particularly the file vignettes.defs of package hyperSpec (https://r-forge.r-project.org/scm/viewvc.php/Vignettes/?root=hyperspec).

BTW: I find it polite to mention that some definitions etc. are executed silently and where people can find it.

Cheers,

Claudia
