\title{ plot method for outCoDa objects }
\description{
Plots the Mahalanobis distance.
}
\usage{
\method{plot}{outCoDa}(x, y, ...)
}
\arguments{
\item{x}{ object from class \sQuote{outCoDa} }
\item{y}{ ... }
\item{\dots}{ ... }
}
\details{
The dashed line indicates the (1 - alpha) quantile of the Chi-squared distribution. Observations with Mahalanobis distance greater than this quantile could be considered as
compositional outliers.
