FrobError-methods: Frobenius error for all factorization ranks

In hdsu-bioquant/ButchR: Non-Negative Matrix Factorization Suite

Frobenius error for all factorization ranks

Description

Returns a data.frame with factorization ranks in the columns, and the Frobenius error for every NMF initialization in the rows.

Usage

FrobError(x, ...)

## S4 method for signature 'ButchR_NMF'
FrobError(x, ...)

## S4 method for signature 'ButchR_integrativeNMF'
FrobError(x, ...)

## S4 method for signature 'ButchR_joinNMF'
FrobError(x, ...)

Arguments

x	an object of class ButchR_NMF, ButchR_joinNMF, or ButchR_integrativeNMF.
...	additional parameters.

Value

data.frame with Frobenius errors

Examples

data("leukemia")
nmf_exp <- run_NMF_tensor(leukemia$matrix, ranks = 2,
method = "NMF",
n_initializations = 2)
FrobError(nmf_exp)
## Not run: 
data("leukemia")
nmf_exp <- run_NMF_tensor(leukemia$matrix, ranks = 2:10,
method = "NMF",
n_initializations = 2)
FrobError(nmf_exp)

## End(Not run)
