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, ...)

Value

a Coe object of same class

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

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