Plot for kernel local significant difference regions
Description
Plot for kernel local significant difference regions for 1- to 3-dimensional data.
Usage
## S3 method for class 'kde.loctest'
plot(x, ...)
Arguments
x |
an object of class kde.loctest (output from kde.local.test )
|
... |
other graphics parameters:
lcol colour for KDE curve (1-d)
col vector of 2 colours. Default is c("purple",
"darkgreen"). First colour: sample 1>sample 2, second colour:
sample 1<sample2.
add flag to add to current plot. Default is FALSE.
rugsize height of rug-like plot (1-d)
add.legend flag to add legend. Default is FALSE (1-d, 2-d).
pos.legend position label for legend (1-d, 2-d)
add.contour flag to add contour lines. Default is FALSE (2-d).
and those used in plot.kde

Details
For kde.loctest objects, the function headers are
## univariate
plot(x, lcol, col, add=FALSE, xlab="x", ylab, rugsize, add.legend=TRUE,
pos.legend="topright", ...)
## bivariate
plot(x, col, add=FALSE, xlab="x", ylab="y", add.contour=FALSE,
add.legend=TRUE, pos.legend="topright", ...)
## trivariate
plot(x, col, add=FALSE, xlab="x", ylab="y", zlab="z", box=TRUE, axes=TRUE,
alphavec=c(0.5, 0.5), ...)
Value
Plots for 1-d and 2-d are sent to graphics window. Plot for 3-d is
sent to RGL window.
