plot.cv.compCL {Compack}R Documentation

Plot the cross-validation curve produced by "cv.compCL" object.

Description

Plot the cross-validation curve with its upper and lower standard deviation curves.

Usage

## S3 method for class 'cv.compCL'
plot(x, xlab = c("log", "-log", "lambda"), trim = FALSE, ...)

Arguments

x

fitted "cv.compCL" object.

xlab

what is on the X-axis, "log" plots against log(lambda) (default), "-log" against -log(lambda), and "lambda" against lambda.

trim

logical; whether to use the trimmed result. Default is FALSE.

...

other graphical parameters.
