[R] calculating the spacial autocorrelation for poisson data

[Ronaldo Reis-Jr.]

Hi,

I have some count data. I try to calculate if exist spacial
auto-correlation. In geoR I make:

variog.p50 <- variog(p50,uvec=c(1:10))

but I think that the correct is using geoRglm

I try:

covariog.p50 <- covariog(p50,uvec=c(1:10))

But it is not the same  calculation.

I new in geostatistic, I'm stunding.

The semivariogram I know how to interpret the output and graphics, but dont
with covariance.

Any help are welcome

Thanks
Ronaldo
