hetsurr (version 1.0)

hetsurr.plot: Constructs plots of the treatment effect, residual treatment effect, and proportion explained as a function of the continuous baseline covariate

Description

Constructs plots of the treatment effect, residual treatment effect, and proportion explained as a function of the continuous baseline covariate

Usage

hetsurr.plot(hetsurr.results, xlab.name = "Baseline Covariate", placement = "bottomleft")

Arguments

hetsurr.results

This is a list produced by the hetsurr.fun function.

xlab.name

This is the label for the x-axis; default is "Baseline Covariate".

placement

This is the placement for the legend; default is "bottomleft".
