Hi, When I was running the function "loess(y~x, span=0.0020)", I got a warning message "k-d tree limited by memory. ncmax= 4231" Does that mean the function has not been computed correctly ? If it has not, is there any way to adjust it so that it will do correctly ? Thanks. Rupen. *************** If you fail to plan, you are planning to fail. _________________________________________________________________ Download music tracks from 95c here:

It was computed a little inaccurately. You can alter many things: see ?loess.control, especially its first item. *However*, that span is so small that this makes little sense, with too few neighbours for any visually apparent smoothing.
