Ermmm....
First, if I read the help pages correctly, the two base loess implementations
have different defaults and use quite different calculations, so different
results are very much to be expected.
Second, the brief description of the poblem made me twitch. What are your
coordinates? A matrix of gene interactions _sounds_ like something that one
should not put a smoother through; gene ID is usually categorical. To be
sensible you'd need some continuous quantitative x- and y- coordinates.
