cocplot: Plot the colour opponent coding diagram

Description

Produces a plot based on the colour opponent coding diagram of Backhaus (1991).

Usage

cocplot(cocdata, labels = TRUE, lab.cex = 0.9, tick.loc = c(-12, -9, -6, -3, 3, 6, 9, 12), achro = FALSE, achrosize = 0.8, achrocol = "grey", margins = c(1, 1, 2, 2), square = TRUE, ...)

Arguments

cocdata

(required) a data frame, possibly a result from the categorical function, containing values for 'x' and 'y' coordinates as columns (labeled as such).

labels

plot axis labels? Defaults to TRUE.

lab.cex

character expansion factor for category labels when labels = TRUE).

tick.loc

a numeric vector specifying the location of tick marks on x & y axes.

achro

should a point be plotted at the origin (defaults to 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.
