Checking NMF Algorithm

Description

nmfCheck enables to quickly check that a given NMF algorithm runs properly, by applying it to some small random data.

Usage

nmfCheck(method = NULL, rank = max(ncol(x)/5, 3), x = NULL, seed = 1234, ...)

Arguments

method: name of the NMF algorithm to be tested.
rank: rank of the factorization
x: target data. If NULL, a random 20 x 10 matrix is generated
seed: specifies a seed or seeding method for the computation.
...: other arguments passed to the call to nmf.

Value

the result of the NMF fit invisibly.

Examples



# test default algorithm
nmfCheck()

# test 'lee' algorithm
nmfCheck('lee')
