\usage{
ternary_pairs(x, ...)

\S4method{ternary_pairs}{matrix}(x, margin = NULL, ...)

\S4method{ternary_pairs}{data.frame}(x, margin = NULL, ...)
}
\arguments{
\item{x}{A \code{\link{matrix}} or a \code{\link{data.frame}}. Columns are converted to \code{numeric}
in the same way that \code{\link[=data.matrix]{data.matrix()}} does.}

\item{...}{Further arguments to be passed to \code{\link[graphics:arrows]{graphics::arrows()}}.}

\item{margin}{A \code{\link{character}} string or an \code{\link{integer}} giving the index of
the column to be used as the third part of the ternary plots. If \code{NULL}
(the default), marginal compositions will be used (i.e. the geometric mean
of the non-selected parts).}
}
\value{
\code{ternary_pairs()} is called it for its side-effects.
}
\description{
Produces a matrix of ternary plots.
}
\examples{
## Data from Aitchison 1986
## Ternary plots with marginal compositions
ternary_pairs(boxite)

## Ternary plots with endite
ternary_pairs(boxite, margin = "E")
