Build a hex bin plot

Source: R/HexBinPlot.R

Build a hex bin plot with rational color coding.

HexBinPlot(
  d,
  xvar,
  yvar,
  title,
  ...,
  lightcolor = "#deebf7",
  darkcolor = "#000000",
  bins = 30,
  binwidth = NULL,
  na.rm = FALSE
)

Arguments

d

data frame
xvar

name of x variable column
yvar

name of y variable column
title

plot title
...

not used, forces later arguments to bind by name
lightcolor

light color for least dense areas
darkcolor

dark color for most dense areas
bins

passed to geom_hex
binwidth

passed to geom_hex
na.rm

passed to geom_hex

Value

a ggplot2 hexbin plot

Details

Builds a standard ggplot2 hexbin plot, with a color scale such that dense areas are colored darker (the default ggplot2 fill scales will color dense areas lighter).

The user can choose an alternate color scale with endpoints lightcolor and darkcolor; it is up to the user to make sure that lightcolor is lighter than darkcolor.

Requires the hexbin package.

Examples


if(requireNamespace("hexbin", quietly = TRUE)) {
   set.seed(634267)
   dframe = data.frame(x = rnorm(1000), y = rnorm(1000))
   print(HexBinPlot(dframe, "x", "y", "Example hexbin"))

   diamonds = ggplot2::diamonds
   print(HexBinPlot(diamonds, "carat", "price", "Diamonds example"))

   # change the colorscale
    print(HexBinPlot(diamonds, "carat", "price", "Diamonds example",
                     lightcolor="#fed98e",
                     darkcolor="#993404"))
