plot.cvdglars: Plot from a cvdglars object

Description

Plots the cross-validation curve, and upper and lower standard deviation curves, as a function of the used $\gamma$ values.

Usage

## S3 method for class 'cvdglars':
plot(x, ...)

Arguments

x

fitted cvdglars object.

...

additional graphical parameters to plot.

Details

A plot for a cvdglars object is produced. The plot shows the curve of the cross-validation deviance and the upper and lower standard deviation curves. The optimal value of the $\gamma$ parameter, which corresponds to the minimum of the cross-validation deviance, is identified by a vertical dashed red line.
