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

Description

plot.OptGS_opchar() plots values from a group-sequential clinical trial operating characteristic object for a normally distributed primary outcome.

Usage

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

Arguments

x	An object of class OptGS_opchar, as returned by opchar.
...	For compatability with the generic.
output	A logical variable indicating whether to return output from the function.

Value
