Gabor,
Thanks for the advice. Using the 'rowlabel' switch works, but when
used with the 'collabel' switch, I received the following error in
Latex 2e:
! LaTeX Error: Illegal character in array arg.
The line that LaTeX has issue with is:
\multicolumn{1}{observed}{uh}&
The entire table looks like:
\begin{table}[!tbp]
\begin{center}
\begin{tabular}{lrr}\hline\hline
\multicolumn{1}{l}{predicted}&
\multicolumn{1}{observed}{uh}&
\multicolumn{1}{l}{uh~}
\tabularnewline \hline
uh&$201$&$30$\tabularnewline
uh~&$ 6$&$10$\tabularnewline
\hline
\end{tabular}
\end{center}
\end{table}
I know that LaTeX has issues with unescaped tildes, but it does not
explain why I get this error.

Try the latex function in the Hmisc package. Using the state.*
variables built into R for sake of example:
library(Hmisc)
latex(table(state.division, state.region), rowlabel = "X", collabel =
"Y", file = "")

Dear R-philes:
I am having an issue with exporting contingency tables with
xtable(). I set
up a contingency and convert it to a matrix for passing to xtable()
as shown
below.
v.cont.table <- table(v_lda$class, grps,
dnn=c("predicted", "observed"))
v.cont.mat <- as.matrix(v.cont.table)
Both produce output as follows:
observed
predicted uh uh~
uh 201 30
uh~ 6 10
However, when I construct the latex table with xtable(v.cont.mat),
I get a
good table without the headings of "predicted" and "observed".
\begin{table}[ht]
\begin{center}
\begin{tabular}{rrr}
\hline
& uh & uh\~{} \\
\hline
uh & 201 & 30 \\
uh\~{} & 6 & 10 \\
\hline
\end{tabular}
\end{center}
\end{table}
Question: is there any easy way to retain or re-insert the
dimension names
from the contingency table and matrix?
