Plot the cross-validated curve produced by cv.ernet

Description

Plots the cross-validated curve, and upper and lower standard deviation curves, as a function of the lambda values used. This function is modified based on the plot.cv.glmnet function from the glmnet package.

Usage

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

Arguments

x

fitted cv.ernet object

sign.lambda

either plot against log(lambda) (default) or its negative if sign.lambda=-1.

...
