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 set, I don't get zero values. It seems that every time I run my script, interpolation is preformed differently. Since I have same problem with different packages I suppose that there is problem with R in Ubuntu. I don't have the same problem with scripts when running them in R in Windows7. Also, sometimes on the graphs appears white line across the image, and it has nothing to do with image resolution. Can you please tell me is it a bug in those packages, or is there some different problem. Thx! -------------- next part -------------- A non-text attachment was scrubbed...
