tools::buildVignettes(), which is used by 'R CMD build', tries to
protect against this by always resetting the working directory after
weave:ing and tangle:ing a vignette, cf.
http://svn.r-project.org/R/trunk/src/library/tools/R/Vignettes.R.
tools::buildVignette() [no plural 's'], which is used by 'R CMD
Sweave' (which is what Tim uses), should also do this, but looking at
the code, this may only work properly if argument 'dir' is an absolute
path, which it may not be the case (not sure). I've just submitted a
bug report PR#15530
[https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=15530] with a
patch on this.
There may also be related issues in the utils::Sweave drivers (looks
like code running during garbage collection) - I'll let someone else
look into that. But, undoing setwd():s in the vignette should solve
this, iff that's what behind this in the first place.
