signature_cosine_similarity: Signature cosine similarity

In popopo19/excerno: Fillter out somatic mutations generated by the Formalin-Fixed Paraffin-Embedded (FFPE) tissue preservation technique from cancer tissue

Signature cosine similarity

Description

Calculating the cosine similarity between a vector of mutations and a mutational signature

Usage

signature_cosine_similarity(mutations.vector, signature.matrix)

Arguments

mutations.vector	A vector of mutations. Type string.
siganture.matrix	A signature matrix

Value

A number between 0 and 1

Examples

library(MutationalPatterns)
library(tidyverse)

cosmic.sig4 <- as.matrix(get_known_signatures()[,4])
sample.sig4 <- create_signature_sample_vector(cosmic.sig4)
signature_cosine_similarity(sample.sig4, cosmic.sig4)
