This methods applies column-wise on the coe of any
Coe object but relies on a function that can be used on any matrix. It
simply uses rnorm with the mean and sd calculated for every column (or row).
For a Coe object, on every colum, randomly generates coefficients values
centered on the mean of the column, and with a sd equals to it standard deviates
multiplied by rate.
Usage
breed(x, ...)
"breed"(x, margin = 2, size, rate = 1, ...)
"breed"(x, size, rate = 1, ...)
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
