The answer below solved my fist question, so I edit my question as follows:

I have a shapefile given with the attributes lat, lon, elevation and temperature.

So far I have a script that interpolates only the temperature data:

#read shapefile:    
shape <- readOGR("C:/Users.../Testarea.gdb", "temperature_data")
#grid shapefile:
shape.grid <- spsample(shape, type = "regular", offset = (c1,1))
gridded(shape.grid) <- TRUE

test <- krige(Temperatur~1, shape, shape.grid)

Now my problem is that I should also need to consider the elevation, since the temperature is often dependant on this parameter. How can I do this?

  • With r questions it's useful to provide a minimal reproducible example so we can test solutions. Can you edit your question either to include a link to your shapefile, either in its original location or use a file sharing site? – Phil Mar 4 '16 at 16:47
  • I'm really curious... Are you attempting this in the R-ArcGIS Bridge, or running in straight R? – Priscilla Mar 4 '16 at 21:39
  • I will upload a shape file tomorrow. I have a R-Arcgis bridge running but first I want to do a stand-alone script and then maybe later edit it to implement the script into arcgis :) – Moritz Mar 5 '16 at 15:20
  • I uploaded my .gdb with the shapefile to my google drive: drive.google.com/… Any help would be greatly appreciated :) – Moritz Mar 6 '16 at 18:59

    @Phil did you get the chance to try a solution to interpolate the data considering the elevation? :) – Moritz Mar 10 '16 at 7:47

You didn't pass shape.grid to krige. Try:

test = krige(Temperatur ~ 1, shape, shape.grid)

Your example does not work as is, ssample should have been spsample. For your second question, you will need a grid with elevation data.

  • Thanks, i edited my sample from ssample to spsamle. Still, your script edit does not give me the kriged data, instead i only get a grid. I uploaded my gdb in the comments to my original post, maybe you could take a look at it? Thanks for your help! – Moritz Mar 6 '16 at 19:09
  • use spplot instead of plot; I edited my answer. – Edzer Pebesma Mar 7 '16 at 9:10
  • Thank you! The spplot works just fine. Now the only trouble is that i did not consider the elevation yet. – Moritz Mar 7 '16 at 11:04
