Plot a colour hexagon

Description

Produces a colour hexagon plot.

Usage

hexplot(
  hexdata,
  achro = TRUE,
  labels = TRUE,
  sectors = c("none", "fine", "coarse"),
  sec.col = "grey",
  out.lwd = 1,
  out.lty = 1,
  out.lcol = "black",
  labels.cex = 1,
  achrosize = 0.8,
  achrocol = "grey",
  square = TRUE,
  ...
)

Arguments

hexdata	(required) a data frame, possibly a result from the colspace() or hexagon() function, containing values for the 'x' and 'y' coordinates as columns (labeled as such)
achro	should a point be plotted at the origin (defaults to TRUE)?
labels	logical. Should the name of each cone be printed next to the corresponding vertex?
sectors	plot the bee-hue sector dividers? Options are: "none": No sectors (default) "fine": 36 10-degree sectors "coarse": six bee-hue sectors (blue, blue-green, green, uv-green, uv, uv-blue).
sec.col	line colour of hue sector dividers. Defaults to "grey".
out.lwd, out.lcol, out.lty	graphical parameters for the plot outline.
labels.cex	size of the arrow labels.
achrosize	size of the point at the origin when achro = TRUE (defaults to 0.8).
achrocol	color of the point at the origin achro = TRUE (defaults to 'grey').
square	logical. Should the aspect ratio of the plot be held to 1:1? (defaults to TRUE).
...	additional graphical options. See par().
