Get/Set a Static Variable in NMF Algorithms

Description

This function is used in iterative NMF algorithms to manage variables stored in a local workspace, that are accessible to all functions that define the iterative schema described in NMFStrategyIterative.

It is specially useful for computing stopping criteria, which often require model data from different iterations.

Usage

  staticVar(name, value, init = FALSE)

Arguments

`name`	Name of the static variable (as a single character string)
`value`	New value of the static variable
`init`	a logical used when a `value` is provided, that specifies if the variable should be set to the new value only if it does not exist yet (`init=TRUE`).
