Gery,

You have created two loess functions, one which accepts two arrays of doubles, and one which accepts a geometry and a double precision number.

You have two error messages :

There is no function that I can see that accepts a single list of double values… you might want to count your brackets..!

There is no function that I can see that accepts a geometry only… you have defined one that accepts geometry and a double precision number.
