custom_cssls: Custom CSSLS.

In mutSignatures: Decipher Mutational Signatures from Somatic Mutational Catalogs

Description

This function contributes to solving a nonnegative least square linear problem using normal equations and the fast combinatorial strategy from Van Benthem et al. (2004). This implementation is similar to that included in the NMF R package by Renaud Gaujoux and Cathal Seoighe, and it is tailored to the data used in the mutational signature analysis. For more info, see: https://CRAN.R-project.org/package=NMF

Usage

custom_cssls(CtC, CtA, Pset)

Arguments

CtC	numeric matrix
CtA	numeric matrix
Pset	nueric matrix

Value

a numeric matrix

Examples

x <- mutSignatures:::getTestRunArgs(testN = "custom_cssls")
y <- mutSignatures:::custom_cssls(CtC = x$CtC, CtA = x$CtA, Pset = x$Pset)
y
