Description Usage Arguments Details Value See Also Examples

Plots the second stage sample sizes of two-stage adaptive single-arm trial designs determined using des_adaptive(). The values of n₂(s_n₁)) are plotted.

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

`x`	An object of class `"sa_des_adaptive"`, as returned by `des_adaptive()`.
`...`	Additional objects of class `"sa_des_adaptive"`. 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 second stage sample sizes of multiple two-stage adaptive single-arm clinical trial designs for a single binary primary endpoint.

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_adaptive, opchar_adaptive, and their associated plot family of functions.

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