Hi All,

I had some species count of a particular area. with the corresponding plot
numbers and location info. Anyone have idea on how to do Kiriging(any type)
on it


Sample data format:
Latitute, Longitude, PlotID, SpeciesCount
18.5         32.3         105       100
....
...
..

Please tell me how to do kriging over this data

Also I had made a shapefile (point data) from this using QGIS

and also exported into GRASS GIS.

But I am stuck with creating variogram . I followed this GRASS tutorial
[1]. When I start to plot I am getting some error reg response variable.

"no response variable present in formula"


here "el" is a species count from the vector data loaded in grass

loading of data from GRASS shell and also creating spatialDataFrame was fine


g <- gstat(id="el", formula=el ~ 1, data=x)

## view a variogram with specified parameters
plot(variogram(g, width=250, cutoff=10000, map=FALSE))
