Venn

Description

Venn diagram (also known as Euler diagram). Minimizes sum of squared residuals to find the best overlap. Where no diagram appears, it is likely that there is a problem with the inputs. This is a wrapper for http://www.buildingwidgets.com/blog/2015/6/5/week-22-d3vennr, which in turn is a wrapper for http://www.benfrederickson.com/venn-diagrams-with-d3.js/.

Usage

Venn(
  x = NULL,
  weights = NULL,
  colors = c("#1f77b4", "#ff7f0e", "#2ca02c", "#d62728", "#9467bd", "#8c564b", "#e377c2",
    "#7f7f7f", "#bcbd22", "#17becf"),
  opacity = NULL,
  global.font.family = "Arial",
  data.label.font.autocolor = TRUE,
  data.label.font.color = "#FFFFFF",
  data.label.font.family = global.font.family,
  data.label.font.size = 14,
  hovertext.font.family = global.font.family,
  hovertext.font.size = 14,
  values.hovertext.format = ""
)

Arguments

x	A data.frame logical (converted to logical using >= 1 if not) or a JSON-like list.
weights	An optional vector of weights, or, the name or, the name of a variable in x. It may not be an expression.
colors	A character vector specifying the color of each circle.
opacity	Numeric; Opacity of circles as an alpha value (0 to 1).
global.font.family	Font family of all text elements. These can be overriden for individual text elements.
data.label.font.autocolor	Logical; Whether font color should be automatically set to the same as the circle color. When this is true, data.label.font.color is ignored.
data.label.font.color	Font color of data labels (ignored if data.label.font.autocolor).
data.label.font.family	Font family of data labels.
data.label.font.size	The font size of the labels. Defaults to 20.
hovertext.font.family	Font family of hovertext (i.e tooltips).
hovertext.font.size	Font size of hovertext in pixels.
values.hovertext.format	A string representing a d3 formatting code. See https://github.com/mbostock/d3/wiki/Formatting#numbers. This option only applies when x is a data.frame.

Examples

Venn(list(
   list("sets"= list(0), "label"= "Like", "size"= 100),
   list("sets"= list(1), "label"= "Love", "size"= 50),
   list("sets"= list(2), "label"= "Dislike", "size"= 100),
   list("sets"= list(3), "label"= "Hate", "size"= 50),
   list("sets"= list(0, 1), "size"= 50),
   list("sets"= list(0, 2), "size"= 0),
   list("sets"= list(2, 3), "size"= 50)))
