plot.nnlasso: Plot of regularization path

In nnlasso: Non-Negative Lasso and Elastic Net Penalized Generalized Linear Models

Description

Produces a plot of entire regularization path from a 'nnlasso' object obtained using ‘nnlasso’ function.

Usage

## S3 method for class 'nnlasso'
plot(x,xvar=c("lambda","L1norm","fraction of norm"),...)

Arguments

x	A ‘nnlasso’ object obtained using ‘nnlasso’ function.
xvar	What should be on x-axis? xvar="lambda" produces a plot of regularization path with respect to lambda, xvar="L1norm" produces a plot of regularization path with respect to L1 norm of coefficients and xvar="fraction of norm" produces a plot of regularization path with respect to fraction of norm of coefficients. Default is xvar="L1norm".
...	Optional graphical parameters to matplot() function

Value

A plot of regularization path is produced.
