plot.TrialDesign: Trial Design Plotting

Description

Plots a trial design.

Usage

# S3 method for TrialDesign
plot(
  x,
  y,
  main = NA_character_,
  xlab = NA_character_,
  ylab = NA_character_,
  type = 1,
  palette = "Set1",
  theta = seq(-1, 1, 0.01),
  nMax = NA_integer_,
  plotPointsEnabled = NA,
  legendPosition = NA_integer_,
  showSource = FALSE,
  ...
)

Arguments

x

The trial design, obtained from getDesignGroupSequential, getDesignInverseNormal or getDesignFisher.

y

Not available for this kind of plot (is only defined to be compatible to the generic plot function).

main

The main title.

xlab

The x-axis label.

ylab

The y-axis label.

type

The plot type (default = 1). The following plot types are available:

• 1: creates a 'Boundaries' plot

• 3: creates a 'Stage Levels' plot

• 4: creates a 'Type One Error Spending' plot

• 5: creates a 'Power and Early Stopping' plot

• 6: creates an 'Average Sample Size and Power / Early Stop' plot

• 7: creates an 'Power' plot

• 8: creates an 'Early Stopping' plot

• 9: creates an 'Average Sample Size' plot

palette

The palette, default is "Set1".

theta

A vector of theta values.

nMax

The maximum sample size.

plotPointsEnabled

If TRUE, additional points will be plotted.

legendPosition

The position of the legend. By default (NA_integer_) the algorithm tries to find a suitable position. Choose one of the following values to specify the position manually:

• -1: no legend will be shown

• NA: the algorithm tries to find a suitable position

• 0: legend position outside plot

• 1: legend position left top

• 2: legend position left center

• 3: legend position left bottom

• 4: legend position right top

• 5: legend position right center

• 6: legend position right bottom

showSource

If TRUE, the parameter names of the object will be printed which were used to create the plot; that may be, e.g., useful to check the values or to create own plots with plot.

...

Optional ggplot2 arguments.

Value

A ggplot2 object.

Examples

# NOT RUN {
design <- getDesignInverseNormal(kMax = 3, alpha = 0.025, 
    typeOfDesign = "asKD", gammaA = 2, 
    informationRates = c(0.2, 0.7, 1), 
    typeBetaSpending = "bsOF")

if (require(ggplot2)) {
    plot(design) # default: type = 1
}
