Dear R-loveRs:
I normally worked with data from fisheries. I only made variograms with den=
sity.
I mean=2C my geodata was with the vectors: X=2C Y and Density. All of them =
were numbers about the format:
x.xx=2C y.yy=2C d.dd =3B 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 1=
007.675 4.28
However=2C right now I am trying to make variograms with geodata from occur=
rence frequencies. Then=2C my data has the following format:
x.xx=2C y.yy=2C d.dd. For instance:
xUTMkm yUTMkm frecuency450.6532 1008.625 11450.5304 1012.401 1=
450.6268 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 dir=
ectional variograms.
What do you think about this graphs? (mainly=2C about the cloud variogram) =
. Is it possible to work with such variograms like the ones that we 'normal=
ly' see.I realize that there is a kind of two clouds there. But I have deci=
ded to ignore the farthest group (because it is too far from the beginning =
distance). Did I decided correctly?.
Thanks in advance for youR advices.
