dist.hamming: Pairwise Distances from Sequences

Description

dist.hamming and dist.logDet compute pairwise distances for an object of class phyDat. dist.ml fits distances for amino acid models.

Usage

dist.hamming(x, ratio = TRUE)
dist.logDet(x)
dist.ml(x, model="JC69",...)

Arguments

x

an object of class dist.logDet

ratio

compute uncorrected ('p') distance or character difference.

model

One of "JC69", "WAG", "JTT", "LG" or "Dayhoff"

...

Further arguments passed to or from other methods.

Value

• an object of class dist
