Number Of Subjects Plotting

Source: R/class_event_probabilities.R

Plots an object that inherits from class NumberOfSubjects.

# S3 method for class 'NumberOfSubjects'
plot(
  x,
  y,
  ...,
  allocationRatioPlanned = NA_real_,
  main = NA_character_,
  xlab = NA_character_,
  ylab = NA_character_,
  type = 1L,
  legendTitle = NA_character_,
  palette = "Set1",
  plotPointsEnabled = NA,
  legendPosition = NA_integer_,
  showSource = FALSE,
  plotSettings = NULL
)

Arguments

x

The object that inherits from NumberOfSubjects.

y

An optional object that inherits from EventProbabilities.

...

Optional plot arguments. At the moment xlim and ylim are implemented for changing x or y axis limits without dropping data observations.

allocationRatioPlanned

The planned allocation ratio n1 / n2 for a two treatment groups design, default is 1. Will be ignored if y is undefined.

main

The main title.

xlab

The x-axis label.

ylab

The y-axis label.

type

The plot type (default = 1). Note that at the moment only one type is available.

legendTitle

The legend title, default is "".

palette

The palette, default is "Set1".

plotPointsEnabled

Logical. 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

Logical. 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 the base R plot function. Alternatively showSource can be defined as one of the following character values:

  • "commands": returns a character vector with plot commands

  • "axes": returns a list with the axes definitions

  • "test": all plot commands will be validated with eval(parse()) and returned as character vector (function does not stop if an error occurs)

  • "validate": all plot commands will be validated with eval(parse()) and returned as character vector (function stops if an error occurs)

Note: no plot object will be returned if showSource is a character.

plotSettings

An object of class PlotSettings created by getPlotSettings().

Value

Returns a ggplot2 object.
