nnlasso (version 0.3)

plot.nnlasso: Plot of regularization path

Description

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

Usage

"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".
