Thank you for appreciated reply, I explane you exactly what I want to do with this R code attached. I want to adapt this code to my data to build an isohyet map. But i have some difficulties to adapt it to my case. I will be very happy when you will help my to adapt this R code (attached) to my case. You can find attached the you R code and my data file. Best regards
