Hexagonal Binning Plot

Displays a two-dimensional density estimate using hexagonal bins. Observations are aggregated into hexagons and coloured according to the number of observations falling into each cell.

Usage

plotHexbin(
  x,
  y,
  bins = 30,
  col = NULL,
  border = NA,
  grid = FALSE,
  xlim = NULL,
  ylim = NULL,
  main = NULL,
  xlab = "",
  ylab = "",
  ...
)

Arguments

x

numeric vector of x-values.

y

numeric vector of y-values.

bins

number of hexagons across the x-axis.

col

colours used for the count scale. If NULL, a default sequential palette is used.

border

border colour of the hexagons.

grid

logical or list controlling the background grid.

xlim

limits for the x-axis.

ylim

limits for the y-axis.

main

main title.

xlab

label for the x-axis.

ylab

label for the y-axis.

...

additional graphical parameters passed to .applyParFromDots().

Value

Invisibly returns a list containing the computed hexbin object and the original x and y.
