\title{
function for use in graphs that are used with the psfrag package in LaTeX
}
\description{
\code{tex} is a little function to save typing when including TeX
commands in graphs that are used with the psfrag package in LaTeX to
typeset any LaTeX text inside a postscript graphic. \code{tex}
surrounds the input character string with \samp{\tex[options]\{\}}.
This is especially useful for getting Greek letters and math symbols
in postscript graphs. By default \code{tex} returns a string with
\code{psfrag} commands specifying that the string be centered, not
rotated, and not specially enlarged or shrunk.
}
\usage{
tex(string, lref='c', psref='c', scale=1, srt=0)
}
\arguments{
\item{string}{
a character string to be processed by \code{psfrag} in LaTeX.
}
\item{lref}{
LaTeX reference point for \code{string}. See the \code{psfrag}
documentation referenced below. Default is \code{"c"} for centered
(this is also the default for \code{psref}).
}
\item{psref}{
PostScript reference point.
}
\item{scale}{
scall factor, default is 1
}
\item{srt}{
rotation for \code{string} in degrees (default is zero)
}
}
\value{
\code{tex} returns a modified character string.
