Arguments

x

A mc or a mcnode object.

margin

The dimension on which applying the function. Maybe "all" (default) to apply the function on all values, "var" to apply the function on the variability dimension, "unc" to apply the function on the uncertainty dimension, or "variates" to apply the function on the variates. Watch out: do not use 'var' for 'variates'

fun

The function to be applied. When applied to a vector of length n, fun should return a vector of length n or 1.

...

Optionnal arguments to fun.
