Adds a new biplot layer for a specified pair of principal components. The pair is sorted automatically (e.g. c(5, 3) becomes c(3, 5)). Both PC indices must be between 1 and p (the number of variables), and the pair must not already exist.

Usage

Arguments

object

A bipl5_biplot object

eigenvectors

Integer vector of length 2 giving the PC pair (e.g. c(4, 5))

Value

A new bipl5_biplot with the additional mdsDisplay appended
