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

Description

Plots the stopping boundaries of group sequential single-arm trial designs determined using des_gs(). 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_gs'
plot(x, ..., output = F)

Arguments

x	An object of class "sa_des_gs", as returned by des_gs().
...	Additional objects of class "sa_des_gs". 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 group sequential single-arm clinical trial designs for a single binary primary endpoint, 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.

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

Examples

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