In mjg211/OptGS: Optimal and Near-optimal Group-sequential Designs for Clinical Trials with Continuous Outcomes

Description

plot.OptGS_des() plots the stopping boundaries from a group-sequential clinical trial design object for a normally distributed primary outcome. Plots are produced by stage and by sample size.

Usage

## S3 method for class 'OptGS_des'
plot(x, ..., output = F)

Arguments

x	An object of class OptGS_des, as returned by des_gs, des_nearopt, des_opt, or build.
...	For compatability with the generic.
output	A logical variable indicating whether to return output from the function.

Value

A list containing each of the input variables (subject to internal modification), along with the following elements:

• plots: A list containing the stopping boundary plotting objects.
