FRCC (version 1.1.0)

plot_variables: Plot variables in the Canonical Factor Loadings Space

Description

This function plots the variables used in the FRCCA as points in a two-dimensional plane in which the axis are the canonical factor loadings selected by the user.

Usage

plot_variables(res.mrcc, i, j, inner_circle_radius = 0.5, text_size = 0.8)

Value

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

Arguments

res.mrcc

List containing a canonical structure provided by the function frcc.

i

Canonical Factor Loadings which will be used as the horizontal axis.

j

Canonical Factor Loadings which will be used as the vertical axis.

inner_circle_radius

Radius of the circle which is used to determine which variables are significant. Only the significant variables will be labeled.

text_size

Character expansion factor for the labels of the variables.
