In Momocs: Morphometrics using R

Permutes and breed Coe (and others) objects

Description

This methods applies permutations column-wise on the coe of any Coe object but relies on a function that can be used on any matrix. For a Coe object, it uses sample on every column (or row) with (or without) replacement.

Usage

perm(x, ...)

## Default S3 method:
perm(x, margin = 2, size, replace = TRUE, ...)

## S3 method for class 'Coe'
perm(x, size, replace = TRUE, ...)

Arguments

x	the object to permute
...	useless here
margin	numeric whether 1 or 2 (rows or columns)
size	numeric the required size for the final object, same size by default.
replace	logical, whether to use sample with replacement

Value

a Coe object of same class

m <- matrix(1:12, nrow=3)
m
perm(m, margin=2, size=5)
perm(m, margin=1, size=10)

bot.f <- efourier(bot, 12)
bot.m <- perm(bot.f, 80)
bot.m
