[Jeff D. Hamann]

When I tried to read all the entries (after searching the FAQ) for "row
names xtable", I get


START-INFO-DIR-ENTRY * R FAQ: (R-FAQ). The R statistical system ...
... xtable* Export data to LaTeX and HTML tables. ... For dropping the row

I wasn't able to follow the link. I'd like to use xtable to generate latex
tables for using with Sweave and can't figure out how to not include the row
names. When I attempt to NULL out the row names using,

but cannot follow the links. Browser tells me the page is unavailable. When
I attempt to blank out the row names using,

rownames(summary.table) <- NULL

I get the following error

> rownames(rta) <- NULL
Error in "dimnames<-.data.frame"(`*tmp*`, value = dn) :
 invalid dimnames given for data frame

the resulting (incorrect) table appears as,

\begin{table}[ht]
\begin{center}
\begin{tabular}{rlr}
\hline
 & site.index & acres \\
\hline
1 &  80 & 20.90 \\
2 &  90 & 64.42 \\
...blah, blah, blah...
8 & 150 & 53.32 \\
9 & 170 & 0.69 \\
\hline
\end{tabular}
\end{center}

with the rownames. How do I get them out?

I'm stuck. Help.

Jeff.
