plotCritDifferences

Plot critical differences for a selected measure.

Description

Plots a critical-differences diagram for all classifiers and a selected measure. If a baseline is selected for the Bonferroni-Dunn test, the critical difference interval will be positioned around the baseline. If not, the best performing algorithm will be chosen as baseline.

The positioning of some descriptive elements can be moved by modifying the generated data.

Usage

plotCritDifferences(obj, baseline = NULL, pretty.names = TRUE)

Arguments

`obj`	(`critDifferencesData`) Result of `generateCritDifferencesData()`.
`baseline`	(`character(1)`): (`learner.id`) Overwrites baseline from `generateCritDifferencesData()`! Select a `learner.id` as baseline for the critical difference diagram, the critical difference will be positioned around this learner. Defaults to best performing algorithm.
`pretty.names`	(`logical(1)`) Whether to use the short name of the learner instead of its ID in labels. Defaults to `TRUE`.

Value

ggplot2 plot object.
