  Calculates the number of negative, zero, positive and missing values in a <code><a rd-options="base" href="/link/numeric?package=matrixStats&version=0.50.2&to=base" data-mini-rdoc="base::numeric">numeric</a></code> vector.  For <code><a rd-options="base" href="/link/double?package=matrixStats&version=0.50.2&to=base" data-mini-rdoc="base::double">double</a></code> vectors, the number of
  negative and positive infinite values are also counted.


internal

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 weightedMedians().
