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

matrixStats (version 0.12.2)

Methods that Apply to Rows and Columns of a Matrix

Description

Methods operating on rows and columns of matrices, e.g. col/rowMedians(), col/rowRanks() and col/rowSds(). There are also some vector-based methods, e.g. binMeans(), madDiff() and weightedMedians(). All methods have been optimized for speed and memory usage.
