spikeslab (version 1.1.6)

plot.spikeslab: Plots for Spike and Slab Analysis

Description

Plots either the gnet solution path or the cross-validated mean-squared-error (the latter only applies when cross-validation is used).

Usage

# S3 method for spikeslab
plot(x, plot.type = c("path", "cv"), breaks = FALSE, ...)

Arguments

x

An object of class spikeslab.

plot.type

Choosing "path" produces a plot of the gnet solution path. The choice "cv" produces the mean-squared error plot. The latter applies only to objects from a cv.spikeslab call.

breaks

If TRUE, then vertical lines are drawn at each break point in the gnet solution path.

...

Further arguments passed to or from other methods.
