Plotting output from a sparse regression.

Description

Function for plotting coefficients from sparsereg analysis.

Usage

## S3 method for class 'sparsereg'
plot(x,...)

Arguments

x

Object from output of class sparsereg.

...

Additional items to pass to plot. Options below.

Details

The function returns up to three plots in one figure. Each plot corresponds with main effects, interaction effects, and two-way interactions. Additional options to pass below.

main1, main2, main3 Main titles for plots of main effects, interactive effects, and two-way interactions.

xlabel Label for x-axis.
