\title{Insert a piece of LaTeX into a HTML file}
\description{
This makes use of \code{AsciiMathML} javascript functions. Standard LaTeX input will be turned into MathML and displayed through any brower extension that can handle MathML (such as MathPlayer)
}
\usage{
as.latex(x, label=NULL,
inline=ifelse(is.null(label), TRUE, FALSE), count=ifelse(is.null(label), FALSE, TRUE))
\method{HTML}{latex}(x, file = HTMLGetFile(), ...)
}
\arguments{
\item{x}{ String containing mathematics in a LaTeX notation }
\item{file}{ HTML target output file}
\item{label}{ String - Label to be displayed before the equation}
\item{inline}{ Boolean - Place of the equation within the output flux - see details}
\item{count}{ Boolean - Should the equation be numbered or not? }
\item{\dots}{ ... }
}
\details{
Mathematical notations will be translated in MathML by the \code{AsciiMathML} javascript program of Peter Jipsen. Note that his functions allow translating equations with a notation simpler than LaTeX (see his page on \code{AsciiMathML} for details). Pieces of LaTeX could be put \emph{inline} (within text) or on a single line : same opposition that the one between $...$ and $$...$$. In order to work, a reference to the javascipt file has to be present within the HTML file \bold{and} the HTML body tag has also to include \code{onload="translate()"}. All the necessary stuff is included in \code{\link{HTMLInitFile}}.
