Draw radial plot for a data frame with positive integer-valued points

Description

This function draws a radial plot for a data frame, plotting positive integer-valued points over concentric circles, with points located more centrally representing higher values.

Usage

radialPlot(
  valuesDF,
  title = NULL,
  valueLegendTitle = "Value",
  groupLegendTitle = NULL,
  extraCircles = 0,
  palette = rpColors(length(unique(valuesDF[, 3]))),
  labelSize = 3,
  pointSize = 0.8,
  legendTitleSize = 10,
  legendTextSize = 10,
  labelRepulsion = 1,
  labelPull = 0,
  maxOverlaps = 15,
  breakDensity = 6,
  seed = 50,
  ...
)

Arguments

valuesDF	A data frame with names on the first column and positive integers on the second column.
title	Plot title.
valueLegendTitle	Legend title corresponding to the positive integer column.
groupLegendTitle	Legend title corresponding to the categorical column.
extraCircles	Number of circles drawn beyond those required to include the points.
palette	Color palette.
labelSize	Label size.
pointSize	Point size.
legendTitleSize	Legend title size.
legendTextSize	Legend text size.
labelRepulsion	Repulsion strength between labels.
labelPull	Attraction strength between a text label and its data point.
maxOverlaps	Maximum number of allowed overlaps.
breakDensity	Factor used in calculating the number of breaks for the values legend. Higher values of this argument add more breaks to the legend, but no breaks at a distance below 1 will be allowed.
seed	Random seed.
...	Additional arguments passed to centerTitle.

Value

An object of class gg.

Examples

valuesDF <- data.frame(Protein = paste0('P', seq(20)),
Value = sample(10, 20, replace=TRUE),
Group = sample(3, 20, replace=TRUE))
radialPlot(valuesDF, groupLegendTitle='Group')
