\code{data.frame}. Use \code{"l"}, \code{"r"}, and \code{"c"} to
denote left, right, and center alignment, respectively. Use
- \code{"p\{3cm\}"} etc. for a LaTeX column of the specified width. For
+ \code{"p{3cm}"} etc. for a LaTeX column of the specified width. For
HTML output the \code{"p"} alignment is interpreted as \code{"l"},
ignoring the width request. Default depends on the class of
\code{x}. }
