plot.Daim: Plotting method for Daim Objects

In Daim: Diagnostic accuracy of classification models.

Description

Plot a Daim object generated by the Daim function.

Usage

## S3 method for class 'Daim'
plot(x, method=NULL, all.roc=FALSE, color="red",
     alpha=0.25, type="s", xlab="False positive rate", 
     ylab="True positive rate", main=NULL, add=FALSE, 
     legend = FALSE, ...)

Arguments

x	an object of class Daim.
method	kind of the estimation of the ROC curve: '0.632+', '0.632', 'loob', 'cv', 'sample'
all.roc	logical. Should ROC curves from all samples be plotted ?
color	the color used to draw the ROC curve.
alpha	semi-transparent color: see rgb.
type	what type of plot should be drawn: see argument 'type' by the function plot.
xlab	a title for the x axis: see title.
ylab	a title for the y axis: see title.
main	a main title for the plot, see also title.
add	logical specifying if roc-area should be added to an already existing plot.
legend	add legend to plot.
...	graphical parameters can be given as arguments to 'plot'.

Examples

  library(Daim)
  data(Daim.data1)
  perform <- performDaim(Daim.data1$prob.oob, Daim.data1$labels, Daim.data1$prob.app)
  summary(perform)

  par(mfrow=c(2,2))
  plot(perform, method="0.632+", legend=TRUE)
  plot(perform, method="sample")
  plot(perform, method="0.632+", main="Comparison between methods")
  plot(perform, method="0.632", col="blue", add=TRUE)
  plot(perform, method="loob", col="green", add=TRUE)
  legend("bottomright", c("0.632+","0.632","loob"),
         col=c("red","blue","green"), lty=1, inset=0.01)
  plot(perform, all.roc=TRUE)
