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, ...)
# S3 method for default
perm(x, margin = 2, size, replace = TRUE, ...)
# S3 method for Coe
perm(x, size, replace = TRUE, ...)

Arguments

x

margin

numeric whether 1 or 2 (rows or columns)

size

numeric the required size for the final object, same size by default.

replace

m
perm(m, margin=2, size=5)
perm(m, margin=1, size=10)

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