renozao/applyBy: Subset-wise apply functions to aggregate rows or columns of matrix-like objects

This package defines a function applyBy that enables applying a function along margins of matrix-like objects separately within groups of columns/rows defined by factor(s), e.g., computing aggregated summary statistics. It is essentially a wrapper around functions from the the matrixStats package, which provide very fast alternative implementation to the base aggregate function.
