Checking NMF Algorithm

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

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

`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`.

the result of the NMF fit invisibly.

# test default algorithm
nmfCheck()

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