\usage{
ternary_hull(x, y, z, ...)

\S4method{ternary_hull}{numeric,numeric,numeric}(x, y, z, ...)

\S4method{ternary_hull}{ANY,missing,missing}(x, y, z, ...)
}
\arguments{
\item{x, y, z}{A \code{\link{numeric}} vector giving the x, y and z ternary coordinates
of a set of points. If \code{y} and \code{z} are missing, an attempt is made to
interpret \code{x} in a suitable way (see \code{\link[grDevices:xyz.coords]{grDevices::xyz.coords()}}).}

\item{...}{Further arguments to be passed to \code{\link[graphics:polygon]{graphics::polygon()}}.}
}
\value{
\code{ternary_hull()} is called it for its side-effects.
}
\description{
Computes and draws the convex hull of the set of points specified.
}
\examples{
## Convex hull
## Data from Aitchison 1986
ternary_plot(lava, panel.first = ternary_grid(5, 10))
ternary_hull(lava, border = "red")
