Aha, works for me too. Sorry, I probably should have been able to work that out myself.

So: not so much a bug, more a wish as it might be good if the vignette code checked for multiple vignettes with the same name and returned a choice or a message warning you that there are multiples. Should I do a follow-up to that bug?

Many thanks to you and all for R: incredible resource.
