plot.cv.rgam: Plot the cross-validation curve produced by "cv.rgam" object
In relgam: Reluctant Generalized Additive Models

Description Usage Arguments Details See Also Examples

Plots the cross-validation curve produced by a cv.rgam object, along with upper and lower standard deviation curves, as a function of the lambda values used. The plot also shows the number of non-zero features picked for each value of lambda.

1 2	## S3 method for class 'cv.rgam' plot(x, sign.lambda = 1, ...)

`x`	Fitted "`cv.rgam`" object.
`sign.lambda`	Either plot against `log(lambda)` (default) or `-log(lambda)` (if `sign.lambda = -1`).
`...`	Other graphical parameters to plot.

A plot is produced and nothing is returned.
