[Bug]: Arguments problem in computeAsymetry

[thomasarsouze]

What happened?

computeAsymetry function currently takes direction as an argument, but is never used. Also, this argument is not described in the document.

What is the expected behaviour ?

Minimal Complete Verifiable Example

Propose a solution

We should remove direction argument to the function and from all the calls to this function in the code / tests / vignettes

Anything else we need to know?

Environment

@BaptisteDlp and @thomaspibanez : can you confirm that direction argument is not needed in this function ? Just need your confirmation before taking care of doing the code modifications.
