plotImpHistory function

Plot Boruta object as importance history

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

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.

Returns

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)
