\title{Plot Method for MVR objects}
\description{
  \code{plot.mvr} plots predictions, coefficients, scores, loadings,
  biplots, correlation loadings or validation plots (RMSEP curves, etc.).
}
\usage{
\method{plot}{mvr}(x, plottype = c("prediction", "validation", "coefficients",
                     "scores", "loadings", "biplot", "correlation"), \dots)
}
\arguments{
  \item{x}{an object of class \code{mvr}.  The fitted model to plot.}
  \item{plottype}{character.  What kind of plot to plot.}
  \item{\dots}{further arguments, sent to the underlying plot functions.}
}
\details{
  The function is simply a wrapper for the underlying plot functions
  used to make the selected plots.  See \code{\link{predplot.mvr}},
  \code{\link{validationplot}}, \code{\link{coefplot}},
  \code{\link{scoreplot}}, \code{\link{loadingplot}},
  \code{\link{biplot.mvr}} or \code{\link{corrplot}} for details.  Note
  that all arguments except \code{x} and \code{plottype} must be named.
}
\value{
  \code{plot.mvr} returns whatever the underlying plot function returns.
