| mat2tex {sfsmisc} | R Documentation |
“Translate” an R matrix (like object) into a LaTeX table,
using \begin{tabular} ....
mat2tex(x, file= "mat.tex", nam.center = "l", col.center = "c",
append = TRUE, digits = 3, title)
x |
a matrix |
file |
names the file to which LaTeX commands should be written |
nam.center |
character specifying row names should be center;
default "l". |
col.center |
character (vector) specifying how the columns should
be centered; must have values from c("l","c","r"); defaults
to "c". |
append |
logical; if FALSE, will destroy the file
file before writing commands to it; otherwise (by default),
simply adds commands at the end of file file. |
digits |
integer; setting of options(digits=..) for
purpose of number representation. |
title |
a string, possibly using LaTeX commands, which will span the columns of the LaTeX matrix |
No value is returned. This function, when used correctly, only writes LaTeX commands to a file.
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 ..).
mex <- matrix(c(pi,pi/2,pi/4,exp(1),exp(2),exp(3)),nrow=2, byrow=TRUE,
dimnames = list(c("$\pi$","$e$"),c("a","b","c")))
mat2tex( mex, title="$\pi, e$, etc." )
## The last command produces the file "mat.tex" containing
##> \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.
mat2tex(mex, stdout(), col.center = c("r","r","c"))
