Dear all! 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

Dear all! I am using wireframe function from lattice package. Is it possible to remove box around the plot but to keep axis (x, y, z)? Thanks in advance! [[alternative HTML version deleted]]

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.

I am using the wireframe function from lattice package. The problem that I have is very interesting. Namely, this is my code: x= seq(-pi, pi, len = 20) y=seq(-pi, pi, len = 20) xyz= expand.grid(x = x, y = y) xyz$z=sin(sqrt(xyz$x^2 +xyz$y^2)) trellis.par.set("axis.line",list(col="transparent")) trellis.par.set("panel", list(col="transparent"))

This is some interesting: > -8^(1/3) [1] -2 > x=(-8:8) > y=x^(1/3) > y [1] NaN NaN NaN NaN NaN NaN NaN NaN 0.000000 1.000000 [11] 1.259921 1.442250 1.587401 1.709976 1.817121 1.912931 2.000000 So, can anybody explain this?! (Why is x[1]^(1/3)=y[1]=NaN, but -8^(1/3)=-2?) Thx!!! [[alternative HTML version deleted]]
