| calcchanges {convevol} | R Documentation |
Calculates all phenotypic changes that occur on all branches of a phylogeny.
Description
Calculates the Euclidean distance between all ancestors and descendants on a phylogeny to reconstruct the phenotypic changes that occur along all edges of a phylogeny.
Usage
calcchanges(phyl, phendata)
Arguments
phyl |
The phylogeny of interest in phylo format |
phendata |
A matrix of phenotypic data for all tips, with taxa in rows and characters in columns. |
Details
Calculates the Euclidean distance between all ancestors and descendants on a phylogeny to reconstruct the phenotypic changes that occur along all edges of a phylogeny.
Value
A vector in which each element represents an edge of the phylogeny, and the values are the magnitudes of evolutionary change that occur along those edges.
