Hello, I'm using R for classifying remote sensed data. I finally managed to apply different knn-methods to the data. Now I have a Dataframe with X, Y, and Z columns. Exp.: X Y Z 475477.1 7485303.29 46.62 Is there an easy way to export such dataframe into am Esri compatible format like Arcgrid, img, tiff etc.?? Many thanks, Paul
