autoplot.ph2simon {VisualizeSimon2Stage}

Plot Simon's Two-Stage Design

Description

Plot ph2simon object using ggplot2.

Usage

## S3 method for class 'ph2simon'
autoplot(object, ...)

## S3 method for class 'ph2simon'
autolayer(
  object,
  type = c("minimax", "optimal", "n1", "maximax"),
  n1 = stop("must provide `n1`"),
  n = stop("must provide `n`"),
  r1 = stop("must provide `r1`"),
  r = stop("must provide `r`"),
  pu = stop("must provide `pu`"),
  pa = stop("must provide `pa`"),
  ...
)

Arguments

object

ph2simon object

...

potential parameters, currently not in use

type

character scalar, one of 'minimax', 'optimal', 'n1' and 'maximax'

n1, n

(optional) integer scalars, Stage-1 sample size n_1 and total sample size n. Overridden if object is given

r1, r

(optional) integer scalars, number of response in Stage-1 r_1 and overall r required exclusively, i.e., passing Stage-1 means observing >r_1 response. Overridden if object is given

pu, pa

double scalars, see function ph2simon

Value

Function autoplot.ph2simon returns a ggplot object.

Function autolayer.ph2simon returns a list of ggproto and labels.

Examples

library(clinfun)
(x = ph2simon(pu = .2, pa = .4, ep1 = .05, ep2 = .1)) 
class(x)
autoplot(x, type = 'minimax')
autoplot(x, type = 'optimal')
autoplot(x, type = 'n1')
autoplot(x, type = 'maximax')

# example with r1 = 0
(des = ph2simon(pu = .05, pa = .3, ep1 = .05, ep2 = .2))
autoplot(des, type = 'optimal')
autoplot(des, type = 'minimax')
