+@code{DelayedMatrix} objects from the @code{DelayedArray} package.  It
+contains high-performing functions operating on rows and columns of
+@code{DelayedMatrix} objects, e.g. @code{colMedians}, @code{rowMedians},
+@code{colRanks}, @code{rowRanks}, @code{colSds}, and @code{rowSds}.  Functions
+are optimized per data type and for subsetted calculations such that both
+memory usage and processing time is minimized.")
