search for: tpsfit

Dear R users, I was wondering how I can convert a raster image (that made R through interpolation) into an ascii or csv format? this is the last line of my command p <- interpolate(r, tpsfit) So p is my raster file which I want to convert into ascii or csv Many thanks Regards Mintewab

The output suggests that the smoothing parameter (lambda) is very low (5.632e-05). I have also attached the rest of the output from...
