Description

Create a pie chart

Usage

pieChart(
  data,
  value,
  label,
  colorCategory = "Paired",
  innerRadius = 0,
  outerRadius = "auto",
  padRadius = 0,
  padAngle = NULL,
  cornerRadius = 0,

)

Arguments

data	The data frame to consider.
value	The numeric variable to consider.
label	The labeling variable to consider.
colorCategory	A D3 categorical color scheme, you can find more here <https://github.com/d3/d3-scale-chromatic#categorical>. Defaults to 'Paired'
innerRadius	The size of the inner radius of the pie. Defaults to 0. Set the inner radius to a higher value to plot a donut chart.
outerRadius	The size of the outer radius of the pie.
padRadius	From the D3 official documentation, The pad radius compute the fixed linear distance separating adjacent arcs, defined as padRadius * padAngle.
padAngle	Optional. From the D3 official documentation, the padAngle is used to set the padding angle between consecutive arcs.
cornerRadius	From the D3 official documentation, the value of the corner radius for rounded corners. If the corner radius is greater than zero, the corners of the arc are rounded using circles of the given radius. Defaults to 0.
labelFont	The font family of the legend. Defaults to 'sans-serif'.
title	Optional. The title of the plot.
titleFontSize	The font size of the plot title. Defaults to 22.
font	The font family to consider for the titles. Defaults to "Verdana, Geneva, Tahoma, sans-serif".
bgcol	The background color of the SVG. Defaults to "white".
opacity	The color opacity of the pie (from 0 to 1). Defaults to 1.
labelHeight	The height of the legend. Defaults to 18.
width	Optional. The width of the SVG output.
height	Optional. The height of the SVG output.

Value

A SVG pie chart

Examples

library(dplyr) # needed for the starwars data frame

# starwars is part of the dplyr data frame
mini_starwars <- starwars %>% tidyr::drop_na(mass) %>%
  sample_n(size = 5) # getting 5 random values

pieChart(
  data = mini_starwars,
  value = "mass",
  label = "name"
)
