[R-sig-Geo] Variogram with frecuencies

[Jimmy Neutrón]

Dear R-loveRs:
I normally worked with data from fisheries. I only made variograms with density.
I mean, my geodata was with the vectors: X, Y and Density. All of them were numbers about the format:
 x.xx, y.yy, d.dd ; for instance
  xUTMkm   yUTMkm Density450.6532 1008.625  11.5450.5304 1012.401   0.48450.6268 1011.887   0450.9767 1006.326   4.03451.1903 1003.006  3.98450.9832 1007.675   4.28

However, right now I am trying to make variograms with geodata from occurrence frequencies. Then, my data has the following format:
 x.xx, y.yy, d.dd. For instance:
  xUTMkm   yUTMkm frecuency450.6532 1008.625     11450.5304 1012.401      1450.6268 1011.887      4450.9767 1006.326      3451.1903 1003.006     15450.9832 1007.675      4
It is the first time that I see such a cloud variogram. I also show the directional variograms.
What do you think about this graphs? (mainly, about the cloud variogram) . Is it possible to work with such variograms like the ones that we 'normally' see.I realize that there is a kind of two clouds there. But I have decided to ignore the farthest group (because it is too far from the beginning distance). Did I decided correctly?.
Thanks in advance for youR advices.
