Description Usage Arguments Details Value Author(s) References Examples

Description

Conducts population aggregate analysis over a matrix of characters of interest.

Usage

1

Arguments

data

A data matrix with columns as characters and rows as individuals.

sppVector

The species vector. See sppVector.

Details

When used on DNA sequences, the function treats gaps as seperate characters.

Value

A matrix with species as rows and characters as columns. Cells give the character state of each species if fixed, or "poly" if the character is polymorphic.
