[R] Best way to select good points in a noisy signal ?

Hello, When I plot y=f(x) from the file xy.txt ( http://www.nabble.com/file/p18773387/xy.txt xy.txt ), I can clearly see a trend. Is there a function or a package able to take the median value of y for an interval of x (x +/- a defined value) to plot nice graph (at least a better one) ?

I'm not quite sure if this is what you mean but have a look at ?lowess or ?smooth. I think you might get want you want if you play around with the parameters in lowess --- On Fri, 8/1/08, Ptit_Bleu [EMAIL PROTECTED] wrote: From: Ptit_Bleu [EMAIL PROTECTED] Subject: [R] Best way to select
