plot.cv.VDA_LE: Plot a cv.VDA_LE object

Description

Plot a the cross validation error across lambda values

Usage

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

Arguments

x

Object of class 'cv.VDA_LE', the result of a call to cv.VDA_LE.

...

Not used.

Details

Plots the k-fold cross validation testing error for values across a different lambda1 and lambda2 values. Use cv.VDA_LE to produce the object of class "cv.VDA_LE".

# load data
data(zoo)

# feature matrix without intercept
x <- zoo[,2:17]

# class vector
y <- zoo[,18]

# lambda vector
lam.vec.1 <- log(2:4)/100
