initialise.UV: Initialising the low-rank matrices U and V

In lgl15/cnmtf: Prioritisation of single nucleotide variants using Corrected non-negative matrix tri-factorisation

Description

This function creates initialisations of U and V. It can also read stored initialisations to speed up the cNMTF algorithm.

Usage

initialise.UV(R, name.init = NULL, work.dat = NULL, k2, k1,
  name.exp = NULL, log.file = NULL)

Arguments

R	Relationship matrix, n x m
name.init	Name of the workspace with initialisations of U and V
work.dat	Folder to read or write a workspace with initialisations
k1, k2	Rank parameters (number of clusters for U and V, respectively)
logfile	Name of a file to write progess/status of this function

Value

U.init, V.init intialisations of U and V.
