plotConf {ORION}

Base Classifier Performance Heatmap

Description

Plots a heatmap that shows base classifier performance.

Usage

plotConf(
  x = NULL,
  classNames = NULL,
  main = "summary of base classifiers",
  xlab = "classes",
  ylab = "base classifiers",
  digits = 3,
  ignore = 0,
  first.colors = c("#f5f5f5", "#b2182b"),
  second.colors = c("#f5f5f5", "#2166ac"),
  other.colors = c("#f5f5f5", "#1b7837"),
  las = 1,
  srt = 30,
  color.key = FALSE,
  cex = 1,
  cex.lab = 1,
  ...
)

Arguments

x

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.

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.

other.colors

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

las

See par.

srt

Angle used to rotate the strings of the x-axis and y-axis labels (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.

Details

This function plots a heatmap of the base classifier performance.

Value

No return value, called to generate the heatmap plot.
