plotImpHistory: Plot Boruta object as importance history

In Boruta: Wrapper Algorithm for All Relevant Feature Selection

Plot Boruta object as importance history

Description

Alternative plot method for Boruta objects, showing matplot of attribute importances over run.

Usage

plotImpHistory(
  x,
  colCode = c("green", "yellow", "red", "blue"),
  col = NULL,
  type = "l",
  lty = 1,
  pch = 0,
  xlab = "Classifier run",
  ylab = "Importance",
  ...
)

Arguments

x	an object of a class Boruta.
colCode	a vector containing colour codes for attribute decisions, respectively Confirmed, Tentative, Rejected and shadow.
col	standard col attribute, passed to matplot. If given, suppresses effects of colCode.
type	Plot type that will be passed to matplot.
lty	Line type that will be passed to matplot.
pch	Point mark type that will be passed to matplot.
xlab	X axis label that will be passed to matplot.
ylab	Y axis label that will be passed to matplot.
...	additional graphical parameter that will be passed to matplot.

Value

Invisible copy of x.

Note

This function will throw an error when x lacks importance history, i.e., was made with holdHistory set to FALSE.

Examples

## Not run: 
library(mlbench); data(Sonar)
#Takes some time, so be patient
Boruta(Class~.,data=Sonar,doTrace=2)->Bor.son
print(Bor.son)
plotImpHistory(Bor.son)

## End(Not run)
