Yes, I have also been bitten by the "upgrade" to xtable, which between 1.4-2 
and 1.4-3 added code to try to be cleverer, but has broken output of LaTeX 
markup directly. The offending code starts around line 177 in print.xtable.R 
(#based on contribution from Jonathan Swinton <jonathan at swintons.net> in e-
mail dated Wednesday, January 17, 2007). I did try to write a 
sanitize.text.function= solution, but failed, and backed off to an earlier 
version. Could the maintainer David Dahl, please address this, and include a 
relevant test? (I would CC him, but am travelling and posting via gmane to keep 
thr thread together - I apologize for pruning, but gmane won't post otherwise).

So a solution is to install an earlier version of xtable from the package 
archives, a harder but feasible task for Windows.
