cor_sparse: Find the Pearson correlation of a sparse matrix efficiently
In dgrtwo/widyr: Widen, Process, then Re-Tidy Data
cor_sparse R Documentation
Find the Pearson correlation of a sparse matrix efficiently
Description
Find the Pearson correlation of a sparse matrix.
For large sparse matrix this is more efficient in time and memory than
cor(as.matrix(x)). Note that it does not currently work on
simple_triplet_matrix objects.
Usage
cor_sparse(x)
Arguments
x
A matrix, potentially a sparse matrix such as a "dgTMatrix" object
