hGraph: Create multiplicity graphs using ggplot2

Description

hGraph() plots a multiplicity graph defined by user inputs. The graph can also be used with the **gMCPLite** package to evaluate a set of nominal p-values for the tests of the hypotheses in the graph

Usage

hGraph(
  nHypotheses = 4,
  nameHypotheses = paste("H", (1:nHypotheses), sep = ""),
  alphaHypotheses = 0.025/nHypotheses,
  m = matrix(array(1/(nHypotheses - 1), nHypotheses^2), nrow = nHypotheses) -
    diag(1/(nHypotheses - 1), nHypotheses),
  fill = 1,
  palette = grDevices::gray.colors(length(unique(fill)), start = 0.5, end = 0.8),
  labels = LETTERS[1:length(unique(fill))],
  legend.name = " ",
  legend.position = "none",
  halfWid = 0.5,
  halfHgt = 0.5,
  trhw = 0.1,
  trhh = 0.075,
  trprop = 1/3,
  digits = 5,
  trdigits = 2,
  size = 6,
  boxtextsize = 4,
  arrowsize = 0.02,
  radianStart = if ((nHypotheses)%%2 != 0) {
     pi * (1/2 + 1/nHypotheses)
 } else {
        pi * (1 + 2/nHypotheses)/2
 },
  offset = pi/4/nHypotheses,
  xradius = 2,
  yradius = xradius,
  x = NULL,
  y = NULL,
  wchar = if (as.character(Sys.info()[1]) == "Windows") {
     "w"
 } else {
     "w"
 }
)

Value

A `ggplot` object with a multi-layer multiplicity graph

Arguments
