plot.ncvreg: Plot coefficients from a ncvreg object

Description

Produces a plot of the coefficient paths for a fitted ncvreg object.

# S3 method for ncvreg
plot(x, alpha=1, log.l=FALSE, shade=TRUE, ...)

Arguments

x

Fitted "ncvreg" model.

alpha

Controls alpha-blending, helpful when the number of covariates is large. Default is alpha=1.
