character (vector) specifying how the columns should be centered; must have
values from c("l","c","r"); defaults to "c".

For S: Vincent Carey 〈vjcarey@sphunix.sph.jhu.edu〉, from a post on Feb.19, 1991 to S-news. Port
to R (and a bit more) by Martin Maechler 〈maechler@stat.math.ethz.ch〉.

latex in package Hmisc is more flexible (but may surprise by its auto-printing ..).
Examples
mex \begin{tabular} {| l|| c| c| c|}
##> \multicolumn{ 4 }{c}{ $\pi, e$, etc. } \\ \hline
##> \ & a & b & c \\ \hline \hline
##> $\pi$ & 3.14 & 1.57 & 0.785 \\ \hline
##> $e$ & 2.72 & 7.39 & 20.1 \\ \hline
##> \end{tabular}
## Now you have to properly embed the contents of this file
## in a LaTeX document -- for example, you will need a
## preamble, the \begin{document} statement, etc.
## Note that the backslash needs protection in dimnames
## or title actions.
