[R-sig-Geo] semivariogram + coordinate units

2008-04-10 Thread Pedro Mardones
Dear list members; I'm a newbie in geostatistics so this question may have an obvious answer that I'm not aware of (sorry about this). I've a grid of points in which the x-axis is measured in cm (from 1 to 20) and the y-axis in meters (from 1 to 20). So basically I have 20 x 20 points to work with.

[R-sig-Geo] variogram maps / newbie

2008-04-07 Thread Pedro Mardones
Dear all; Does anyone knows how to obtain a variogram map using the package geoR? I was able to obtain these plots using the gstat package but the results form the variog function are different to those from variogram function in gstat (I guess that has something to do with the bin and maximum dist
