[O] Problem with babel and R + lattice

[John Hendy]

I have an R block like so:

#+begin_src R

library(lattice)
library(tikzDevice)

=bunch of code=

barchart(side$name~side$x2,groups=side$type,horiz=T,
         xlim=c(0,0.75),col=c("lightblue","yellow"),xlab="Product
Performance (2-box)")

dev.off()
tools::texi2dvi("bar-2b.tex",pdf=T)

#+end_src

The resultant tex file is empty where the tikz code should be and
texi2dvi fails. Any suggestions? If I change my plot to base graphics
with barplot, it works. I'm thinking this is a lattice/babel issue?


Thanks for any input,
John
