\title{Plot ROC curve from a cutpointr or roc_cutpointr object}
\usage{
plot_roc(x, ...)

\method{plot_roc}{cutpointr}(x, display_cutpoint = TRUE, type = "line", ...)

\method{plot_roc}{roc_cutpointr}(x, type = "line", ...)
}
\arguments{
\item{x}{A cutpointr or roc_cutpointr object.}

\item{...}{Additional arguments (unused).}

\item{display_cutpoint}{(logical) Whether or not to display the optimal
cutpoint as a dot on the ROC curve for cutpointr objects.}

\item{type}{"line" for line plot (default) or "step" for step plot.}
}
\description{
Given a \code{cutpointr} object this function plots the ROC curve(s)
per subgroup, if given. Also plots a ROC curve from the output of \code{roc()}.
}
\examples{
opt_cut <- cutpointr(suicide, dsi, suicide)
plot_roc(opt_cut, display_cutpoint = FALSE)

opt_cut_2groups <- cutpointr(suicide, dsi, suicide, gender)
plot_roc(opt_cut_2groups, display_cutpoint = TRUE)

roc_curve <- roc(suicide, x = dsi, class = suicide, pos_class = "yes",
  neg_class = "no", direction = ">=")
plot(roc_curve)
auc(roc_curve)
