[BioC] cosine similarity

[joe j]

Dear All,

I am after a package that would calculate the uncentred correlation
(or cosine similarity; http://en.wikipedia.org/wiki/Cosine_similarity)
between pairs of observations. I know that bioconductor has packages
that compute distance measures such as mahalanobis distance (the
package mdqc does this). Is there any package that calculates cosine
similarity?

Regards,
Joe.
