Description Usage Arguments Value Author(s) See Also Examples

This function produces a plot for two-dimensional categorical data (e.g. individual's ID) to show presence/absence or frequency for each category. The resulting plot is a chequer-board with each square representing a pairwise observation. The square can provide further information on (for example) frequency by colouring and/or by the inclusion of text.

1	categoricalxy(my.data, freqlabs = FALSE, colscheme = "heat", poly.border = FALSE, axes.cex = 1)

`my.data`	A dataframe with 3 columns. The first two columns should be categorical variables (coded as factors), while the third should indicate another dimension such as frequency.
`freqlabs`	Should the values of the z dimension (the 3rd column in my.data) be included as text: TRUE/FALSE
`colscheme`	Colour scheme: options are "heat" (heatmap colours) or "greyscale" (greyscale colours. Any other input will result in black squares with a grey background.
`poly.border`	Defines the borders around the individual squares in the plot. See `polygon` for further details
`axes.cex`	Controls the size of the axis labels.

A categorical x-y plot.
