UPDATE:
Now including the LaTeX math formatting

saxtab <- t( as.data.frame( addmargins( Saxony ) ) )
rownames( saxtab ) <- c( "Males ($k$)", "Families ($n_k$)" )
saxtab <- xtable( saxtab, digits = 0,
caption = "Number of male children in 6115 Saxony families of size 12",
align = "l|rrrrrrrrrrrrrr" )
print( saxtab, caption.placement = "top", include.colnames = FALSE,
hline.after = c( NULL, 0, nrow( saxtab ) ),
sanitize.text.function = function(x) { x } )

\begin{table}[ht]

\caption{Number of male children in 6115 Saxony families of size 12}
\begin{tabular}{l|rrrrrrrrrrrrrr}

Males ($k$) & 0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12 & Sum \\
