\title{Plot method for pumaPCARes objects}
\description{
This is the method to plot objects of class pumaPCARes. It will produce a scatter plot of two of the principal components
}
\usage{
\S4method{plot}{pumaPCARes,missing}(..., firstComponent = 1, secondComponent = 2, useFilenames = FALSE, phenotype = pData(pumaPCARes@phenoData), legend1pos = "topright", legend2pos = "bottomright")
}

\arguments{
  \item{\dots}{Optional graphical parameters to adjust different components of the plot}
  \item{firstComponent}{Integer identifying which principal component to plot on the x-axis}
  \item{secondComponent}{Integer identifying which principal component to plot on the x-axis}
  \item{useFilenames}{Boolean. If TRUE then use filenames as plot points. Otherwise just use points.}
  \item{phenotype}{Phenotype information}
  \item{legend1pos}{String indicating where to put legend for first factor}
  \item{legend2pos}{String indicating where to put legend for second factor}
}
