\section{Helper functions for formatting}\r
The functions \code{xalign}, \code{xdigits}, and \code{xdisplay} are useful for\r
formatting tables in a sensible way. Consider the output produced by the default\r
function(str) gsub("_", "\\_", str, fixed = TRUE))\r

Markup can be included in tables, including in column and row names, by using\r
a custom \code{sanitize.text.function}.\r

+One solution is to use the \verb|array| package, defining new\r
column formats.\r

-\begin{lstlisting}\r
+\begin{verbatim}\r
\newcolumntype{L}[1]{>{\raggedright\let\newline\\\r
\arraybackslash\hspace{0pt}}m{#1}}\r
\newcolumntype{C}[1]{>{\centering\let\newline\\\r

These allow for very sophisticated cell formatting, namely\r
left-aligned, centred, or right-aligned text, with recognition of line\r
breaks for the first three new column types. If these lines are\r
