R: Print two tables with xtable ()

Question

I have data tables (d1 and d2) which I would like to print side by side or on top of each other in latex with their own individual titles. Is it possible to do that directly wit

Answer 1

I would recommend saving the results as two separate tables in different files (see the file= option to print.xtable()), and then input them into your LaTeX document with any command you find appropriate for your layout (tabular, subfloat, minipage, etc.). This is what I do in general, although I generally rely on LaTeX facilities in the Hmisc package. Should you want only to print them as a standalone PDF, use the standalone class for your document.

So, here is an example:

data(tli)
fm1 <- aov(tlimth ~ sex + ethnicty + grade + disadvg, data=tli)
print(xtable(fm1), file="ta.tex", floating=FALSE)
print(xtable(head(tli, n=5)), file="tb.tex", floating=FALSE)

then, a quick tex wrapper (compile with pdflatex):

\documentclass{article}
\usepackage{subfig}
\usepackage{graphicx}

\begin{document}

\begin{table}[ht]
\centering
\subfloat[Table x(a)]{\label{tab:tab1a}\scalebox{.5}{\input{./ta}}}\quad
\subfloat[Table x(b)]{\label{tab:tab1b}\scalebox{.5}{\input{./tb}}}
\caption{Caption about here}
\label{tab:tab1}
\end{table}

\end{document}

Here is the result:

Remove the \scalebox command for default (stacked) layout, unless they are narrow enough to fit at their default size, as noted by @David.
