[R] several odfWeave questions

I believe it does, since this gets passed directly to Sweave.

Yes. There are examples of this in the 'examples' package directory.

Get the latest version form R-Forge. I haven't gotten this fix onto
CRAN yet (I've been on a caret streak lately).

You can set the working directory with the (wait for it...) 'workDir'
argument. Using 'workDir = getwd()' will pack and unpack the files in
the current location and you wouldn't need to worry about setting the
path. I use the temp directory because I started over-wrting files.
