Usage

find_signature_name(signature)

signature

A signature matrix

Value

A string of the most similar signature

Examples

library(tidyverse)

# Load in a signature
cosmic.sigs <- get_known_signatures()
signature.4 <- as.matrix(cosmic.sigs[,4])
rownames(signature.4) <- get_mutation_types()

# Usage
