[Gstat-info] variogram

[Hoogland, Tom]

I use gstat in R for the first time and in the first steps I encounter
this error:

> library(gstat)
Loading required package: sp
> pnt<-read.table("pnt-norg.csv", header=TRUE, sep=",")
> coordinates(pnt) = ~X + Y
> varioghg <- variogram(GHG_NAP ~ 1, pnt)
Error: dimensions do not match: locations 426 and data 159
> summary(pnt)
Object of class SpatialPointsDataFrame
Coordinates:
     min    max
X 228793 229679
Y 566722 567816
Is projected: NA 
proj4string : [NA]
Number of points: 213

The number of locations is indeed 213 as given by summary(pnt) but the
variogram finctions seems to find 426 locations. Can anyone tell me
whats wrong...
