Description Usage Arguments Details Value See Also Examples

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

`x`	An object of class `"sa_des_admissable"`, as returned by `des_admissable()`.
`...`	Included for compatibility with the generic. Not currently used.
`output`	A logical variable indicating whether the outputs described below should be returned.

In addition, admissable design plots are produced to depict in which region of the weight-space each of the designs is optimal, and to illuminate the expected sample size characteristics of the admissable designs.

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_admissable, opchar_admissable, and their associated plot family of functions.

# Find the admissable two-stage designs for the default parameters
des <- des_admissable()
# Plot the stopping boundaries and admissable design plot
plot(des)
