Plotting Routine for Gamsel Cross-Validation Object

Description

Produces a cross-validation curve with standard errors for a fitted gamsel objecty.

Usage

## S3 method for class 'cv.gamsel'
plot(x, sign.lambda = 1, ...)

Arguments

x	cv.gamsel object
sign.lambda	Either plot against log(lambda) (default) against -lambda if sign.lambda=-1.
...	Optional graphical parameters to plot.

Details

A plot showing cross-validation error is produced. Nothing is returned.
