lambda.transform: lambda transformation of matrix
In phytools: Phylogenetic Tools for Comparative Biology (and Other Things)
lambda.transform R Documentation
\lambda transformation of matrix
Description
Internal function for phyl.pca and others.
Usage
lambda.transform(lambda, C)
Arguments
lambda
scalar, usually (but not necessarily) on the interval 0,1.
C
matrix probably returned by vcv.phylo.
Details
Multiplies the off-diagonals of a square matrix by lambda and returns the result.
Value
Typically an among-species phylogenetic variance covariance matrix (e.g., vcv.phylo) in which the off-diagonal elements have been multiplied by lambda.
