nmfSeed: Seeding Strategies for NMF Algorithms

Description

nmfSeed lists and retrieves NMF seeding methods.

getNMFSeed is an alias for nmfSeed.

existsNMFSeed tells if a given seeding method exists in the registry.

Usage

nmfSeed(name = NULL, ...)
  getNMFSeed(name = NULL, ...)
  existsNMFSeed(name, exact = TRUE)

Arguments

name

access key of a seeding method stored in registry. If missing, nmfSeed returns the list of all available seeding methods.

...

extra arguments used for internal calls

exact

a logical that indicates if the access key should be matched exactly or partially.

Details

Currently the internal registry contains the following seeding methods, which may be specified to the function nmf via its argument seed using their access keys:

[object Object],[object Object],[object Object],[object Object]
