Not sure if the performance of apply is so much of a problem, but also from a view of consistency of the provided functions, I think offering such functions would make it more clear and consitent to use R here, because all those functions are then available for row and col and the functionality is appended in the name (Mean, Sum etc.). I think the basic things that should be available woud be: - mean - median - min - max - var - sd If both then are available for rows and columns, this would be fine.
