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

Description

Plots the confidence intervals, and the performance of the confidence interval determination procedures, in a group sequential single-arm trial design for a single binary endpoint determined using ci_gs(). A range of plots are available, of which the confidence intervals and the coverage probability curve will be printed by default.

Usage

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

Arguments

x	An object of class "sa_ci_gs", as returned by ci_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 confidence interval determination procedures for a range of
# possible response probabilities
ci  <- ci_gs(des, pi = seq(0, 1, 0.01))
# Plot the confidence intervals and the determination procedures performance
plot(ci)
