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

You can also check the vegan package: http://cran.r-project.org/web/packages/vegan//index.html

The function vegdist in this package has a variety of dissimilarity (distance) functions, such as manhattan, euclidean, canberra, bray, kulczynski, jaccard, gower, altGower, morisita, horn,mountford, raup , binomial, chao or cao.
