Formatting R arrays in LaTeX Beamer

Question

I have an R array output that I would like to include in a LaTeX beamer slide.

The array is simple enough

, , 1

       [,1] [,2] [,3] [,4] [,5]
 [1,]   NA   NA   NA   NA   NA
 [2,]   NA   NA   NA   NA   NA
 [3,]   NA   NA   NA   NA   NA
 [4,]   NA   NA   NA   NA   NA
 [5,]   NA   NA   NA   NA   NA
 [6,]   NA   NA   NA   NA   NA
 [7,]   NA   NA   NA   NA   NA
 [8,]   NA   NA   NA   NA   NA
 [9,]   NA   NA   NA   NA   NA
[10,]   NA   NA   NA   NA   NA

but seems a nightmare to format quickly and easily using the amsmath package and \begin{array}[cccccc] and \end{array}[cccccc].

Does someone know of a nice solution?

Any assistance is greatly appreciated.

Welcome to TeX.SX! You could use a online table generator https://www.tablesgenerator.com/ — Bobyandbob, Oct 27 '17 at 16:17
Or print the table verbatim: \begin{frame}[fragile]\begin{verbatim}[copy your array here]\end{verbatim}\end{frame}, if needed you can make the text smaller using the solution in https://tex.stackexchange.com/questions/161678/decreasing-font-size-in-verbatim. — Marijn, Oct 27 '17 at 21:54
@Marijn I completely forgot about \verbatim ! Easier than the table generator! — compbiostats, Oct 28 '17 at 01:53
@Marijn Would you like to convert your comment into an answer? — samcarter_is_at_topanswers.xyz, Oct 31 '17 at 14:03

You can use the varbatim environment for data such as program outputs. Note that the beamer frame needs to be fragile for this environment.

The font size can be changed by patching \verbatim@font with etoolbox, as in https://tex.stackexchange.com/a/161713.

MWE:

\documentclass{beamer}
% optional font size setting for verbatim text, can be removed
\usepackage{etoolbox}
\makeatletter
\patchcmd{\@verbatim}
  {\verbatim@font}
  {\verbatim@font\tiny}     % set font size here
  {}{}
\makeatother
% end of optional font size setting

\begin{document}
\begin{frame}[t,fragile]{50 tiny fragile top-aligned NAs}
\begin{verbatim}
       [,1] [,2] [,3] [,4] [,5]
 [1,]   NA   NA   NA   NA   NA
 [2,]   NA   NA   NA   NA   NA
 [3,]   NA   NA   NA   NA   NA
 [4,]   NA   NA   NA   NA   NA
 [5,]   NA   NA   NA   NA   NA
 [6,]   NA   NA   NA   NA   NA
 [7,]   NA   NA   NA   NA   NA
 [8,]   NA   NA   NA   NA   NA
 [9,]   NA   NA   NA   NA   NA
[10,]   NA   NA   NA   NA   NA
\end{verbatim}
\end{frame}
\end{document}

Result:

Note that for displaying source code (e.g., R scripts) it is usually preferred to use packages like listings or minted.
