setNMFSeed: 'NMFSeed' is a constructor method that instantiate 'NMFSeed'...
In renozao/NMF: Algorithms and Framework for Nonnegative Matrix Factorization (NMF)

Description Usage Arguments Methods (by generic)

NMF seeding methods are registered via the function setNMFSeed, which stores them as NMFSeed objects in a dedicated registry.

NMFSeed(key, method, ...)

## S4 method for signature 'character'
NMFSeed(key, method, ...)

## S4 method for signature 'NMFSeed'
NMFSeed(key, method, ...)

setNMFSeed(..., overwrite = isLoadingNamespace(), verbose = TRUE)

removeNMFSeed(name, ...)

`key`	access key as a single character string
`method`	specification of the seeding method, as a function that takes at least the following arguments: object uninitialised/empty NMF model, i.e. that it has 0 rows and columns, but has already the rank requested in the call to `nmf` or `seed`. x target matrix ... extra arguments
`...`	arguments passed to `NMFSeed` and used to initialise slots in the `NMFSeed` object, or to `pkgreg_remove`.
`overwrite`	logical that indicates if any existing NMF method with the same name should be overwritten (`TRUE`) or not (`FALSE`), in which case an error is thrown.
`verbose`	a logical that indicates if information about the registration should be printed (`TRUE`) or not (`FALSE`).
`name`	name of the seeding method.

NMFSeed(key = character): Default method simply calls new with the same arguments.
NMFSeed(key = NMFSeed): Creates an NMFSeed based on a template object (Constructor-Copy), in particular it uses the same name.
