\alias{plotBMRRanksAsBarChart}
\title{Create a bar chart for ranks in a BenchmarkResult.}
\usage{
plotBMRRanksAsBarChart(
bmr,
measure = NULL,
ties.method = "average",
aggregation = "default",
pos = "stack",
order.lrns = NULL,
order.tsks = NULL,
pretty.names = TRUE
)
}
\arguments{
\item{bmr}{(\link{BenchmarkResult})\cr
Benchmark result.}
\item{measure}{(\link{Measure})\cr
Performance measure.
Default is the first measure used in the benchmark experiment.}
\item{ties.method}{(\code{character(1)})\cr
See \link{rank} for details.}
\item{aggregation}{(\code{character(1)}) \cr
\dQuote{mean} or \dQuote{default}. See \link{getBMRAggrPerformances}
for details on \dQuote{default}.}
\item{pos}{(\code{character(1)})\cr
Optionally set how the bars are positioned in ggplot2.
Ranks are plotted on the x-axis.
\dQuote{tile} plots a heat map with \code{task} as the y-axis.
Allows identification of the performance in a special task.
\dQuote{stack} plots a stacked bar plot.
Allows for comparison of learners within and and across ranks.
\dQuote{dodge} plots a bar plot with bars next to each other instead
of stacked bars.}
\item{order.lrns}{(\code{character(n.learners)})\cr
Character vector with \code{learner.ids} in new order.}
\item{order.tsks}{(\code{character(n.tasks)})\cr
Character vector with \code{task.ids} in new order.}
\item{pretty.names}{(\code{logical(1)})\cr
Whether to use the short name of the learner instead of its ID in labels. Defaults to \code{TRUE}.}
}
\value{
ggplot2 plot object.
}
\description{
Plots a bar chart from the ranks of algorithms. Alternatively,
tiles can be plotted for every rank-task combination, see \code{pos}
for details. In all plot variants the ranks of the learning algorithms are displayed on
the x-axis. Areas are always colored according to the \code{learner.id}.
