Nothing
Highperforming 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 vectorbased methods, e.g. binMeans(), madDiff() and weightedMedian().
