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

Description Usage Arguments Details Value See Also Examples

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.

1 2	## S3 method for class 'sa_des_curtailed' plot(x, ..., output = F)

`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.

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.

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.

des_curtailed, opchar_curtailed, and their associated plot family of functions.

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