Hi, how are you? I'm currently using createIntamapObject to create an interpolation object of class 'idw'. The method is working fine but I'm getting a lot of text output in the console which I suspect is slowing things down. I tried to remove it by setting the debug.level parameter in the params list to 0 like this:
interpolacion <- *createIntamapObject(*observations=observaciones, formulaString=tendenciaEspacial, predictionLocations=coordsAInterpolar[sel,], intCRS=params$proj4StringAInterpolar, targetCRS=params$proj4StringAInterpolar, class='idw', *params=list(nclus=nCoresAUsar, nmin=params$nmin, nmax=params$nmax, maxdist=params$maxdist, debug.level = 0)*, outputWhat=outputWhat*)* Is this the right way to do it? I can try to make a reproducible example if it's needed. Thanks in advance! Pablo Ing. Pablo Alfaro Piñeyro MotionSoft Consulting S.R.L.
