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

Description

Plots the operating characteristics of Bayesian-frequentist single-arm trial designs determined using opchar_bayesfreq(). A range of plots are available, of which the expected sample size and power curves will be printed by default.

Usage

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

Arguments

x	An object of class "sa_opchar_bayesfreq", as returned by opchar_bayesfreq().
...	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.

See Also

des_bayesfreq, and opchar_bayesfreq, and their associated plot family of functions.

Examples

# Find the optimal group sequential design for the default parameters
des    <- des_bayesfreq()
# Determine operating characteristics for a range of response probabilities
opchar <- opchar_bayesfreq(des, pi = seq(0, 1, 0.01))
# Plot the expected sample size and power curve
plot(opchar)
