basis-coef: Get/Set the matrix factors in a NMF model
Description
basis
and basis<-
are S4 generic functions which respectively
extract and set the matrix of basis vectors (i.e. the first matrix factor)
of a NMF model.
For example, in the case of the standard NMF model $V \equiv WH$,
method basis
will return matrix $W$.
coef
and coef<-
are S4 methods defined for the associated generic
functions from package stats
(See coef).
They respectively extract and set the matrix of mixture coefficients
(i.e. the second matrix factor) of a NMF model.
For example, in the case of the standard NMF model $V \equiv WH$,
method coef
will return matrix $H$.
Methods coefficients
and coefficients<-
are simple aliases for methods
coef
and coef<-
respectively.See Also
