plotBaseClassifier: Base Classifier Performance Heatmap

Description

Plots a heatmap that shows base classifier performance.

Usage

plotBaseClassifier(
  x = NULL,
  classNames = NULL,
  symmetric = FALSE,
  main = "summary of base classifiers",
  xlab = "second class",
  ylab = "first class",
  digits = 3,
  ignore = 0,
  first.colors = c("#f5f5f5", "#8c510a"),
  second.colors = c("#f5f5f5", "#01665e"),
  na.color = c("yellow"),
  las = 1,
  color.key = TRUE,
  cex = 1,
  cex.lab = 1,
  ...
)

Arguments

A Conf object as it is returned by conf-function.

classNames

Vector of the original class names. If not given the class number is used instead.

symmetric

Logical indicating whether a symmetric base classifier (TRUE) is used.

main

See plot.

xlab

A title for the x axis (see plot).

ylab

A title for the y axis (see plot).

digits

Integer indicating the number of decimal places to be used (see round).

ignore

A numeric value between 0 and 1. All confusion and purity values below this number are not written as string into the corresponding element.

first.colors

A 2-element vector of the color for the minimal and maximal class-wise sensitivity of the first class. The color palette is calcuated by an interpolation between the 2 given colors.

second.colors

A 2-element vector of the color for the minimal and maximal class-wise sensitivity of the second class. The color palette is calcuated by an interpolation between the 2 given colors.

na.color

Color, which is used for indicating the empty elements (if the given class is not part of the cascade).

las

See par.

color.key

Specifies whether a color key is drawn (TRUE) or not (FALSE).

cex

See par.

cex.lab

See par.

...

Further arguments passed from other methods.

Value

No return value, called to generate the heatmap plot.

Details

This function plots a heatmap of the base classifier performance.
