plot.statis.plane: Plot a Plane of Observations or 2D Projections

Description

This function generates a two-dimensional scatter plot with centered axes, useful for representing the results of multivariate analyses.

Usage

# S3 method for statis.plane
plot(points, inertia = 100, labels = NULL, title = "")

Value

A ggplot object with the generated plot.

Arguments

points: A matrix, data frame, or a length-2 vector with coordinates (x, y). Must have exactly two columns.
inertia: A number between 0 and 100 indicating the percentage of explained inertia (optional, defaults to 100).
labels: A character vector with labels for the points (optional). Must match the number of rows in points.
title: A text string to be used as the main title of the plot (optional).

Details

The plot includes points, optional labels, Cartesian axes (centered at 0), and a title indicating the percentage of explained inertia.

Examples

Run this code

data(expert1, expert2, expert3)

labels <- c("Expert 1", "Expert 2", "Expert 3")

# If you want to select an specific table or row just set the parameters in the statis function.

res <- statis(list(expert1, expert2, expert3), table.labels = labels)

# Main Plane of Average Individuals
individuals <- res$plane.individuals
plot.statis.plane(individuals$points, individuals$inertia, individuals$labels, individuals$title)

# Main Plane of the Evolution of individuals
evolution <- res$plane.evolution
plot.statis.plane(evolution$points, evolution$inertia, evolution$labels, evolution$title)
