Testing Compatibility of Algorithm and Models

canFit is an S4 generic that tests if an algorithm can fit a particular model.

canFit(x, y, ...)

  ## S4 method for signature 'NMFStrategy,character'
canFit(x, y,
    exact = FALSE)

`x`	an object that describes an algorithm
`y`	an object that describes a model
`...`	extra arguments to allow extension
`exact`	for logical that indicates if an algorithm is considered able to fit only the models that it explicitly declares (`TRUE`), or if it should be considered able to also fit models that extend models that it explicitly fits.

canFit: signature(x = "NMFStrategy", y = "character"): Tells if an NMF algorithm can fit a given class of NMF models
canFit: signature(x = "NMFStrategy", y = "NMF"): Tells if an NMF algorithm can fit the same class of models as y
canFit: signature(x = "character", y = "ANY"): Tells if a registered NMF algorithm can fit a given NMF model
