[R] issue with odfWeave running on Windows XP; question about installing packages under Linux

[Max Kuhn]

Sorry for the delayed response.

An upgrade of the XML package has broken odfWeave; see this thread:

   https://stat.ethz.ch/pipermail/r-help/2011-May/278063.html

That may be your issue. We're working on the problem now. I'll post to
R-Packages when we have a working update. If you like, I can send you
the eventual fixes if you would like to test them.

Thanks,

Max

I sent the info to Max Kuhn privately, but did not get a response after two tries.) My odfWeave reporting system worked fine prior to R2.12 and then the same code that ran fine under R2.11.1 stopped working. Using the very same machine and running the very same code under R2.11.1 it still runs fine today. So, something is not quite right with odfWeave on Windows XP for R > R2.11.1, and I don't know what it is. My "solution" is to keep R2.11.1 around until it can be resolved.
