hexplot: 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", lab.cex = 1, achrosize = 0.8, achrocol = "grey", margins = c(1, 1, 2, 2), square = TRUE, ...)

Arguments

hexdata

(required) a data frame, possibly a result from the 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

plot verticy labels? Defaults to TRUE.

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 hexagon outline.

lab.cex

character expansion factor for category labels when labels = TRUE)

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)

margins

margins for the plot.

square

logical. Should the aspect ratio of the plot be held to 1:1? (defaults to TRUE).

...

additional graphical options. See par.
