nmfModel,formula-method). ibterms, icterms and iterms
respectively return the indexes of the fixed basis terms,
the fixed coefficient terms and all fixed terms, within
the basis and/or coefficient matrix of an NMF model.
nterms, nbterms, and ncterms return,
respectively, the number of all fixed terms, fixed basis
terms and fixed coefficient terms in an NMF model. In
particular: i.e. nterms(object) = nbterms(object) +
ncterms(object).
bterms and cterms return, respectively, the
primary data for fixed basis and coefficient terms in an
NMF model -- as stored in slots bterms and
cterms . These are factors or numeric vectors
which define fixed basis components, e.g., used for
defining separate offsets for different a priori
groups of samples, or to incorporate/correct for some
known covariate.
ibasis and icoef return, respectively, the
indexes of all latent basis vectors and estimated
coefficients within the basis or coefficient matrix of an
NMF model.
