get_lambda: Calculate lambda (biplot)

In Andros-Spica/biplot2d3d: Create and Customize Ordination Plots (Biplots) in 2D and 3D

Description

Calculate the lambda factor to scale biplot dimensions. The code is a snippet of biplot.princomp).

Usage

get_lambda(sdev, n.obs, dimensions = 2, scale = 1, pc.biplot = FALSE)

Arguments

sdev	Data frame containing the stardand deviations along n dimensions
n.obs	number of observations (rows) in the original data
dimensions	The number of dimensions
scale	Numeric, the value defining the degree in which distances between observations have priority over distances between variables (0 = observation-focused, 1 = variable-focused). It corresponds to the argument scale in biplot.princomp.
pc.biplot	Character, indicating the type of biplot transformation of data: "default" and "pc.biplot", corresponding to the transformations performed in biplot.princomp with pc.biplot = FALSE ("default") and pc.biplot = TRUE ("pc.biplot"). If NULL, no processing is performed, assuming that data within ordination_object was previously transformed.
