plot_units {FRCC}

Plots the experimental units in the Canonical Variates Space

Description

This function plots the experimental units used in the FRCCA as points in a two-dimensional plane in which the axis are the canonical variates selected by the user

Usage

plot_units(X, Y, res.mrcc, i, text_size = 0.8, point_size = 2)

Arguments

X

numeric matrix (n by p) which contains the observations on the X variables.

Y

numeric matrix (n by p) which contains the observations on the Y variables.

res.mrcc

List containing a canonical structure provided by the function frcc for the dataset X and Y.

i

Canonical Variate which will be used for the axes (X for horizontal and Y for vertical).

text_size

Character expansion factor for the labels of the experimental units.

point_size

Character expansion factor for the point representing the experimental units.

Value

This function just creates the units plot. It does not return a value.
