staticVar

Name of the static variable (as a single
 character string)

name

value

a logical used when a <code>value</code> is
 provided, that specifies if the variable should be set to
 the new value only if it does not exist yet
 (<code>init=TRUE</code>).

init

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
 <code>NMFStrategyIterative</code>.
It is specially useful for computing stopping criteria,
 which often require model data from different iterations.

Provides a framework to perform Non-negative Matrix
Factorization (NMF). The package implements a set of already published algorithms
and seeding methods, and provides a framework to test, develop and plug
new/custom algorithms. Most of the built-in algorithms have been optimized
in C++, and the main interface function provides an easy way of performing
parallel computations on multicore machines.
