slasso (version 1.0.1)

plot.slasso: Plot the results of the S-LASSO method

Description

This function provides plots of the S-LASSO coefficient function estimate when applied to the output of slasso.fr, whereas provides the cross-validation plots when applied to the output of slasso.fr_cv. In the latter case the first plot displays the CV values as a function of lambda_L, lambda_s and lambda_t, and the second plot displays the CV values as a function of lambda_L with lambda_s and lambda_t fixed at their optimal values.

Usage

# S3 method for slasso_cv
plot(x, ...)
# S3 method for slasso
plot(x, ...)

Value

No return value, called for side effects.

Arguments

x

The output of either slasso.fr_cv or slasso.fr.

...

No additional parameters, called for side effects.
