plot.glmreg: plot coefficients from a "glmreg" object

In mpath: Regularized Linear Models

plot coefficients from a "glmreg" object

Description

Produces a coefficient profile plot of the coefficient paths for a fitted "glmreg" object.

Usage

## S3 method for class 'glmreg'
plot(x, xvar = c("norm", "lambda", "dev"), label = FALSE, shade=TRUE, ...)

Arguments

x	fitted "glmreg" model
xvar	What is on the X-axis. "norm" plots against the L1-norm of the coefficients, "lambda" against the log-lambda sequence, and "dev" against the percent deviance explained.
label	If TRUE, label the curves with variable sequence numbers.
shade	Should nonconvex region be shaded? Default is TRUE. Code developed for all weights=1 only
...	Other graphical parameters to plot

Details

A coefficient profile plot is produced.
