[R-sig-Geo] Empirical Variogram from multiple realizations

[Paulo Justiniano Ribeiro Jr]

Jordan

some (not all) functions of geoR accepts data as matrices and can compute 
variograms for multiple realizations

try organize your $data element as a matrix instead of replicate 
coordinates (in which case you could use the options realisations)

feel free to send me exemple codes if you wish
