nmfAlgorithm lists access keys or retrieves NMF
algorithms that are stored in registry. It allows to list
nmfAlgorithm(name = NULL, version = NULL, all = FALSE, ...)
Access key. If not missing, it must be a
single character string that is partially matched against
the available algorithms in the registry. In this case,
If missing or
version of the algorithm(s) to retrieve.
Currently only value
a logical that indicates if all algorithm keys should be returned, including the ones from alternative algorithm versions (e.g. plain R implementations of algorithms, for which a version based on optimised C updates is used by default).
extra arguments passed to
NMFStrategy object if
all=FALSE, or a named
character vector that contains the access keys of the
matching algorithms. The names correspond to the access
key of the primary algorithm: e.g. algorithm ‘lee’
has two registered versions, one plain R
(‘.R#lee’) and the other uses optimised C updates
(‘lee’), which will all get named ‘lee’.
# list all main algorithms nmfAlgorithm() # list all versions of algorithms nmfAlgorithm(all=TRUE) # list all plain R versions nmfAlgorithm(version='R')
