\title{Plot calibration data using ggplot2.}
\usage{
plotCalibration(obj, smooth = FALSE, reference = TRUE, rag = TRUE,
  facet.wrap.nrow = NULL, facet.wrap.ncol = NULL)
}
\arguments{
\item{obj}{(\link{CalibrationData})\cr
Result of \link{generateCalibrationData}.}

\item{smooth}{(\code{logical(1)})\cr
Whether to use a loess smoother.
Default is \code{FALSE}.}

\item{reference}{(\code{logical(1)})\cr
Whether to plot a reference line showing perfect calibration.
Default is \code{TRUE}.}

\item{rag}{(\code{logical(1)})\cr
Whether to include a rag plot which shows a rug plot on the top which pertains to
positive cases and on the bottom which pertains to negative cases.
Default is \code{TRUE}.}

\item{facet.wrap.nrow, facet.wrap.ncol}{([integer])\cr
Number of rows and columns for facetting. Default for both is `NULL`.
In this case ggplot's `facet_wrap` will choose the layout itself.}
}
\value{
ggplot2 plot object.
