knitr error with Lyx

R Users,


I just upgraded my version of R from R-2.15.0 to R-2.15.2 and installed the latest versions of LyX and MikTex running Windows 7 Ultimate, 64-bit OS.  Prior to the upgrade, I was using Lyx with knitr to generate a document with no problems.  However, after the upgrade, and using the same LyX document, I'm receiving the following error when I attempt to compile the document:

\end{verbatim}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

I have determined that the error is caused when printing the anova results from the anova statement in my R source code, but can't seem to resolve the issue.  Here is an example code chunk that creates the error:

<<NonCP1, fig.width=6, fig.height=4, out.width='.8\\linewidth' ,par=FALSE>>=
#Read in data
y=c( 67, 73, 83, 89, 65, 91, 87, 86, 155, 127, 147, 212, 108, 100, 90, 153, 140, 142, 121, 150, 33, 8, 46, 54 )
temp=as.factor(c(rep(seq(360, 380, 10), each=4), rep(seq(380, 360, -10), each=4)))
coat=as.factor(rep(seq(1, 4), 6))
replicate=as.factor(rep(seq(1, 6), each=4))
#Obtain Factorial/Incorrect Model
o=lm(y~temp*coat)
ano=anova(o)
ano
@


Removing the ano=anova(o) or ano lines in the code chunk allows the document to compile with no problem.  Does anyone else have this problem or did I do something wrong when I migrated to the newer versions?

Thanks, in advance for any help!

Sincerely yours,
