plot.sa_est_gs: Plot the point estimates, and the point estimation procedures...

In mjg211/singlearm: Design and analysis of single-arm clinical trials

Description

Plots the point estimates, and the performance of the point estimation procedure, in a group sequential single-arm trial design for a single binary endpoint determined using est_gs(). A range of plots are available, of which the point estimates and the bias curve will be printed by default.

Usage

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

Arguments

x	An object of class "sa_est_gs", as returned by est_gs().
...	Included for compatibility with the generic. Not currently used.
output	A logical variable indicating whether the outputs described below should be returned.

Value

If output = TRUE, a list containing the following elements is returned

• A list in the slot $plot_des containing the available plots.

• Each of the input variables as specified, subject to internal modification.

Examples

# Find the optimal group sequential design for the default parameters
des <- des_gs()
# Determine the performance of the point estimation procedure for a range of
# possible response probabilities
est <- est_gs(des, pi = seq(0, 1, 0.01))
# Plot the point estimates and the estimation procedure performance
plot(est)
