plot.dkde: Plot for Kernel Density Derivative Estimate

In kedd: Kernel Estimator and Bandwidth Selection for Density and Its Derivatives

Description

The plot.dkde function loops through calls to the dkde function. Plot for kernel density derivative estimate for 1-dimensional data.

Usage

## S3 method for class 'dkde'
plot(x, fx = NULL, ...)
## S3 method for class 'dkde'
lines(x, ...)

Arguments

x	object of class dkde (output from dkde).
fx	add to graphics the true density derivative (class :function), to compare it by the density derivative to estimate.
...	other graphics parameters, see par in package "graphics".

Details

The 1-d plot is a standard plot of a 1-d curve. If !is.null(fx) then a true density derivative is added.

Value

Plot of 1-d kernel density derivative estimates are sent to graphics window.
