plotResiduals

Create residual plots for prediction objects or benchmark results.

Description

Plots for model diagnostics. Provides scatterplots of true vs. predicted values and histograms of the model's residuals.

Usage

plotResiduals(
  obj,
  type = "scatterplot",
  loess.smooth = TRUE,
  rug = TRUE,
  pretty.names = TRUE
)

Arguments

`obj`	(Prediction \| BenchmarkResult) Input data.
`type`	Type of plot. Can be “scatterplot”, the default. Or “hist”, for a histogram, or in case of classification problems a barplot, displaying the residuals.
`loess.smooth`	(`logical(1)`) Should a loess smoother be added to the plot? Defaults to `TRUE`. Only applicable for regression tasks and if `type` is set to `scatterplot`.
`rug`	(`logical(1)`) Should marginal distributions be added to the plot? Defaults to `TRUE`. Only applicable for regression tasks and if `type` is set to `scatterplot`.
`pretty.names`	(`logical(1)`) Whether to use the short name of the learner instead of its ID in labels. Defaults to `TRUE`. Only applicable if a BenchmarkResult is passed to `obj` in the function call, ignored otherwise.

Value

ggplot2 plot object.
