mlr (version 2.6)

plotRankMatrixAsBar: Plot a rank-matrix as a barplot.

Description

Plots a barchart from the ranks of algorithms. Alternatively tiles can be plotted for every rank-task combination, see pos for details. The x-axis accross all plots is the ranks of a learner.id. Areas are always coloured corresponding to the learner.

Usage

plotRankMatrixAsBar(obj, pos = NULL)

Value

ggplot2 plot object.
