With xtable, I'm producing one-way tables from table objects in horizontal form as shown below. I'd like to change the labels used for the rows and move the caption to the top of the table, as is typically standard for tables. I can hand-edit, but would prefer to do it in code.

data(Saxony, package="vcd")
library(xtable)
saxtab <- xtable(t(addmargins(Saxony)), digits=0,
    caption="Number of male children in 6115 Saxony families of size 12")

print(saxtab)
> print(saxtab)
% latex table generated in R 3.0.1 by xtable 1.7-1 package
% Wed Nov 27 09:12:16 2013
\begin{table}[ht]
\centering
\begin{tabular}{rrrrrrrrrrrrrrr}
  \hline
 & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12 & Sum \\
  \hline
1 & 3 & 24 & 104 & 286 & 670 & 1033 & 1343 & 1112 & 829 & 478 & 181 & 45 & 7 & 6115 \\
   \hline
\end{tabular}
\caption{Number of male children in 6115 Saxony families of size 12}
\end{table}
>

The desired form looks like this, with row.names = c("Males ($k$)", "Families ($n_k$)")

\begin{tabular}{l|rrrrrrrrrrrrrr}
  \hline
Males ($k$) & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12 & Sum \\
  \hline
Families ($n_k$) & 3 & 24 & 104 & 286 & 670 & 1033 & 1343 & 1112 & 829 & 478 & 181 & 45 & 7 & 6115 \\
   \hline
\end{tabular}
\end{table}
