cor_sparse

<p>A matrix, potentially a sparse matrix such as a "dgTMatrix" object</p>

<p>Find the Pearson correlation of a sparse matrix.
For large sparse matrix this is more efficient in time and memory than
<code>cor(as.matrix(x))</code>. Note that it does not currently work on
simple_triplet_matrix objects.</p>

Encapsulates the pattern of untidying data into a wide matrix,
performing some processing, then turning it back into a tidy form. This
is useful for several operations such as co-occurrence counts,
correlations, or clustering that are mathematically convenient on wide matrices.
