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

W-Matrix (W-Matrix with smallest frobError)

Description

Return a list of W-Matrices or a W-Matrix for the indicaded rank

Usage

WMatrix(x, k = NULL, ...)

## S4 method for signature 'ButchR_NMF'
WMatrix(x, k = NULL, ...)

## S4 method for signature 'ButchR_integrativeNMF'
WMatrix(x, k = NULL, view_id = NULL, ...)

## S4 method for signature 'ButchR_joinNMF'
WMatrix(x, k = NULL, view_id = NULL, ...)

Arguments

x	an object of class ButchR_NMF, ButchR_joinNMF, or ButchR_integrativeNMF.
k	numeric - factorization rank.
...	additional parameters.
view_id	character vector with views from which to extract W matrices

Value

list of W-Matrices or a W-Matrix for the indicated rank.

Examples

data("leukemia")
nmf_exp <- run_NMF_tensor(leukemia$matrix, ranks = 2,
method = "NMF",
n_initializations = 2)
WMatrix(nmf_exp)
WMatrix(nmf_exp, k = 2)
# For ButchR_NMF objects:
WMatrix(nmf_exp)
WMatrix(nmf_exp, k = 2)
## Not run: 
# For ButchR_integrativeNMF objects:
WMatrix(inmf_exp)
WMatrix(inmf_exp, k = 2)
lapply(WMatrix(inmf_exp, k = 2), head)
WMatrix(inmf_exp, k = 2, view_id = "atac")

## End(Not run)
## Not run: 
# For ButchR_joinNMF objects:
