Transformation NMF Model Objects
t transpose an NMF model, by transposing and
swapping its basis and coefficient matrices:
t([W,H]) = [t(H), t(W)].
## S3 method for class 'NMF' t(x)
x |
NMF model object. |
The function t is a generic defined in the
base package. The method t.NMF defines the
trasnformation for the general NMF interface. This method
may need to be overloaded for NMF models, whose structure
requires specific handling.
x <- rnmf(3, 100, 20) x # transpose y <- t(x) y # factors are swapped-transposed stopifnot( identical(basis(y), t(coef(x))) ) stopifnot( identical(coef(y), t(basis(x))) )
