table2df: Table Mutation Types by Sample.

In mutSignatures: Decipher Mutational Signatures from Somatic Mutational Catalogs

Description

Prepare a molten data.frame starting from a mutation count matrix. Mutation types (rows) are countes for each sample (cols). The results are returned in a 3-column data.frame.

Usage

table2df(dataMatrix, rowLab = "sample", colLab = "feature", valueLab = "count")

Arguments

dataMatrix	a numeric matrix including mutation counts
rowLab	string, name for the column that will be storing row IDs, typically sample IDs
colLab	string, name for the column that will be storing column IDs, typically sample IDs
valueLab	string, name for the column that will be storing mutation count values

Details

This function is part of the user-interface set of tools included in mutSignatures. This is an exported function.

Value

data.frame storing mutation counts by sample
