diff2

A <code><a rd-options="base" href="/link/numeric?package=matrixStats&version=0.57.0&to=base" data-mini-rdoc="base::numeric">numeric</a></code> <code><a rd-options="base" href="/link/vector?package=matrixStats&version=0.57.0&to=base" data-mini-rdoc="base::vector">vector</a></code> of length
N.

A <code><a rd-options="base" href="/link/vector?package=matrixStats&version=0.57.0&to=base" data-mini-rdoc="base::vector">vector</a></code> indicating subset of elements to
operate over. If <code><a rd-options="base" href="/link/NULL?package=matrixStats&version=0.57.0&to=base" data-mini-rdoc="base::NULL">NULL</a></code>, no subsetting is done.

idxs

An <code><a rd-options="base" href="/link/integer?package=matrixStats&version=0.57.0&to=base" data-mini-rdoc="base::integer">integer</a></code> specifying the lag.

An <code><a rd-options="base" href="/link/integer?package=matrixStats&version=0.57.0&to=base" data-mini-rdoc="base::integer">integer</a></code> specifying the order of
difference.

differences

Computes the lagged and iterated differences.

internal

univar

High-performing functions operating on rows and columns of matrices, e.g. col / rowMedians(), col / rowRanks(), and col / rowSds().  Functions optimized per data type and for subsetted calculations such that both memory usage and processing time is minimized.  There are also optimized vector-based methods, e.g. binMeans(), madDiff() and weightedMedian().
