r-cran-matrixstats 0.52.2-2 (amd64 binary) in ubuntu bionic

 This package 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.
