The kriging::kriging is using by default spherical-model. What kind of kriging function (or package) do you recommend?
My data are reanalysis data form the ECMWF ( http://data-portal.ecmwf.int/data/d/interim_daily/levtype=sfc/) and the aim is to interpolate them. I would be grateful, if you could make a recommendation. Thank you. >You may have (near) duplicate points in your data. > >Other packages let you control more when you want to kriging, see the >Spatial task view on CRAN. > >To me, kriging::kriging seems a bit of a black box: does it compute >Euclidian distances from long/lat coordinates directly?
