R: Class for Storing Heterogeneous NMF fits

NMFList-class {NMF} | R Documentation

## Class for Storing Heterogeneous NMF fits

### Description

This class wraps a list of NMF fit objects, which may come from different runs of the function `nmf`, using different parameters, methods, etc.. These can be either from a single run (NMFfit) or multiple runs (NMFfitX).

Note that its definition/interface is very likely to change in the future.

### Methods

algorithm

  `signature(object = "NMFList")`: Returns the method names used to compute the NMF fits in the list. It returns `NULL` if the list is empty.

runtime

  `signature(object = "NMFList")`: Returns the CPU time required to compute all NMF fits in the list. It returns `NULL` if the list is empty. If no timing data are available, the sequential time is returned.

seqtime

  `signature(object = "NMFList")`: Returns the CPU time that would be required to sequentially compute all NMF fits stored in `object`.

  This method calls the function `runtime` on each fit and sum up the results. It returns `NULL` on an empty object.

show

  `signature(object = "NMFList")`: Show method for objects of class `NMFList`
