kerndwd (version 1.0.1)

plot.kerndwd: plot DWD coefficients

Description

Plot the solution paths for a fitted kerndwd object.

Usage

## S3 method for class 'kerndwd':
plot(x, color=FALSE, ...)

Arguments

x

A fitted ``kerndwd"" model.

color

If TRUE, plots the curves with rainbow colors; otherwise, with gray colors (default).

...

Other graphical parameters to plot.

Details

Plots the solution paths as a coefficient profile plot. This function is modified based on the plot function from the glmnet package.
