stepwise.seqs: Simulated sequence alignment from the stepwise package

Description Usage Format Details Source References Examples

Description

Simulated sequence alignment comprised of 30 sequences, each of length 1000 bases.

Usage

1

Format

A 30-by-1000 matrix of mode character. Each row represents a genetic sequence. Each column is a nucleotide in that genetic sequence.

Details

A simulated data set analysed by Graham et al. (2004) to illustrate the stepwise recombination detection methods. The alignment was simulated using Treevolve version 1.3 (Grassly and Holmes 1997). For details on the parameter values used in the simulation, see Graham et al. (2004).
