iteration

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().

rowOrderStats function

This method does <em>not</em> handle missing values, that is, the result
  corresponds to having <code>na.rm=FALSE</code> (if such an argument would
  be available).
