plot.sa_des_fixed: Plot the stopping boundaries of single-stage single-arm trial...

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

Description

Plots the stopping boundaries of single-stage single-arm trial designs determined using des_fixed(). The possible (s,m) states during the trial are plotted in a colour coded manner, to indicate their associated decision rules.

Usage

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

Arguments

x	An object of class "sa_des_fixed", as returned by des_fixed().
...	Additional objects of class "sa_des_fixed". These will be grouped in to a list named "add_des".
output	A logical variable indicating whether the outputs described below should be returned.

Details

Support is available to simultaneously plot the stopping boundaries of multiple applicable designs, using faceting.

Value

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

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

• A tibble in the slot $states containing details of the possible states for each of the designs, and their associated decision rules.

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

Examples

# Find the optimal single-stage design for the default parameters
des    <- des_fixed()
# Plot the stopping boundaries
plot(des)
# Find the optimal single-stage design for a 10% type-I error rate
des_10 <- des_fixed(alpha = 0.1)
# Plot the stopping boundaries for both designs
plot(des, des_10)
