cos_similarity: Gene signature cosine similarity matrix

In cellGeometry: Geometric Single Cell Deconvolution

Gene signature cosine similarity matrix

Description

Computes the cosine similarity matrix from the gene signature matrix of a cellMarkers object or any matrix. Note that this function computes cosine similarity between matrix columns, unlike dist() which computes the distance metric between matrix rows.

Usage

cos_similarity(x, use_filter = NULL)

Arguments

x	Either a matrix or a 'cellMarkers' class or 'deconv' class object.
use_filter	Logical whether to use filtered gene signature.

Value

A symmetric similarity matrix.
