runtime.all,NMFfitXn-method

a logical that indicates if the sequential
  time should be returned if no time data is available in
  slot &#145;runtime.all&#146;.

null

a logical that indicates if a warning
  should be thrown if the sequential time is returned
  instead of the real CPU time.

warning

an object computed using some algorithm, or
  that describes an algorithm itself.

object


  If no time data is available from in slot
  &#145;runtime.all&#146; and argument <code>null=TRUE</code>, then
  the sequential time as computed by <code><a rd-options="" href="/link/seqtime?package=NMF&version=0.20.6" data-mini-rdoc="NMF::seqtime">seqtime</a></code>
  is returned, and a warning is thrown unless
  <code>warning=FALSE</code>.


methods

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.

runtime.all,NMFfitXn-method: Returns the CPU time used to perform all the NMF fits stored in `object`.
