mat2tex: Produce LaTeX commands to print a matrix

Description

``Translate'' an Rmatrix (like object) into a LaTeX table, using \begin{tabular} ....

Usage

mat2tex(x, file="mat.tex", append=TRUE, digits=3, title)

Arguments

x

a matrix

file

names the file to which LaTeX commands should be written

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

Value

• No value is returned. This function, when used correctly, only writes LaTeX commands to a file.

Examples

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.
