Find cosine similarity between two arrays

Question

I\'m wondering if there is a built in function in R that can find the cosine similarity (or cosine distance) between two arrays?

Currently, I implemented my own func

Answer 1

It looks like a few options are already available, but I just stumbled across an idiomatic solution I like so I thought I'd add it to the list.

install.packages('proxy') # Let's be honest, you've never heard of this before.
library('proxy') # Library of similarity/dissimilarity measures for 'dist()'
dist(m, method="cosine")
