ggClassPred: Barplot of the per class accuracies.

Description

The ggClasPred function generates a barplot with the per class accuracies (%) for all the correctly classified and misclassified samples in the classification ensemble.

Usage

ggClassPred(ensObj, position = "stack", displayAll = FALSE, showText = FALSE,  xlabel = NULL, ylabel = NULL, cbPalette = FALSE, fillBrewer = FALSE)

Arguments

ensObj

The classification ensemble (in the form of an R list) as generated by cfBuild

position

The position may be equal to either "stack" or "dodge".

displayAll

Boolean value, by default set to FALSE. When displayAll= FALSE, only the percentages of correctly classified samples are displayed in the barplot. If displayAll = TRUE, the percentages of all classified and missclassified samples are depicted in the barplot.

showText

Boolean value, by default set to FALSE. If showText=TRUE, then the per class accuracies (%) for all classifiers in the ensemble are displayed in the plot.

xlabel

A sub title for the x axis (optional field).

ylabel

A sub title for the y axis (optional field).

cbPalette

If TRUE, enable a color-blind-friendly palette.

fillBrewer

If TRUE, enable a color scale taken from the RColorBrewer package.

## Not run: 
# data(iris)

# irisClass <- iris[,5]
# irisData  <- iris[,-5]
#             
# ens <- cfBuild(irisData, irisClass, bootNum = 100, ensNum = 100, parallel = TRUE, 
#                cpus = 4, type = "SOCK")
# 
# # Show the percentages of correctly classified samples in 
# # a barplot with or without text respectively
# 
# ggClassPred(ens)
# ggClassPred(ens, showText = TRUE)
# 
# # Show the percentages of classified and missclassified samples
# # in a barplot simultaneously with and without text
# 
# ggClassPred(ens, displayAll = TRUE)
# ggClassPred(ens, position="stack", displayAll = TRUE)
# ggClassPred(ens, position="stack", displayAll = TRUE, showText = TRUE)
# 
# # Alernatively, using a dodge position
# ggClassPred(ens, position = "dodge", displayAll = TRUE)
# ggClassPred(ens, position = "dodge", displayAll = TRUE, showText = TRUE)
