Package: CNSigs Type: Package Title: Analysis of Copy Number Signatures Version: 0.1.1 Authors@R: c( person("David", "Tallman", email = "tallman.52@osu.edu", role = "aut"), person("Shawn", "Striker", email = "striker.35@osu.edu", role = c("cre","ctb")), person("Daniel", "Stover", email = "stover.61@osu.edu", role = "cph")) Maintainer: Shawn Striker Description: A workflow to generate and analyze signatures based on copy number data using non-negative matrix factorization (NMF) in an approach similar to that used in mutational signatures. It can be used to extract features from Copy number segment data and use that to find a subset of copy number signatures which can be further used to correlate with other relevant data.
