⚠️There's a newer version (1.5.0) of this package.Take me there.

matrixStats (version 0.10.3)

Methods that apply to rows and columns of a matrix

Description

This packages provides methods operating on rows and columns of matrices, e.g. col/rowMedians() and col/rowRanks(). There are also some vector-based methods, e.g. anyMissing(), weightedMedians(), and binMeans(). The objective is to have all methods being optimized for speed and memory usage.
