\title{Generate threshold vs. performance(s) for 2-class classification.}
\usage{
generateThreshVsPerfData(
obj,
measures,
gridsize = 100L,
aggregate = TRUE,
task.id = NULL
)
}
\arguments{
\item{obj}{(list of \link{Prediction} | list of \link{ResampleResult} | \link{BenchmarkResult})\cr
Single prediction object, list of them, single resample result, list of them, or a benchmark result.
In case of a list probably produced by different learners you want to compare, then
name the list with the names you want to see in the plots, probably
learner shortnames or ids.}
\item{measures}{(\link{Measure} | list of \link{Measure})\cr
Performance measure(s) to evaluate.
Default is the default measure for the task, see here \link{getDefaultMeasure}.}
\item{gridsize}{(\code{integer(1)})\cr
Grid resolution for x-axis (threshold).
Default is 100.}
\item{aggregate}{(\code{logical(1)})\cr
Whether to aggregate \link{ResamplePrediction}s or to plot the performance
of each iteration separately.
Default is \code{TRUE}.}
\item{task.id}{(\code{character(1)})\cr
Selected task in \link{BenchmarkResult} to do plots for, ignored otherwise.
Default is first task.}
}
\value{
(\link{ThreshVsPerfData}). A named list containing the measured performance
across the threshold grid, the measures, and whether the performance estimates were
aggregated (only applicable for (list of) \link{ResampleResult}s).
}
\description{
Generates data on threshold vs. performance(s) for 2-class classification that can be used for plotting.
