cumsum in 3d arrays
Hello!
Is it posible to apply /cumsum()/ along the 3rd dimension of 3D array?
Something like matrlab function - /cumsum (*A*,dim)/ which returns the
cumulative sum of the elements along the dimension of *A* specified by
scalar dim.
Thanks in advance

problem with R (akima, fUtilities) in Ubuntu 10.04

I'm using R 2.12.1 in Ubuntu 10.04.
Problem is that when using functions like interp (package akima) and
akimaInterp (package fUtilities), I get different results every time for
the same data set. I've checked the interpolated results, and two
examples (in attachment) have different sum of NA values. Also when I
subtract the x,y,z values from two interpolations of the same data
