Mac OS 10.3.5, R 2.0.0 latest version of geoR
I have an incomplete 5 x 20 spatial array of samples (60 out of 100 possible locations) for which I would like to calculate directional variograms using variog4(). Unfortunately, I can't get it to return all 4 directions. It returns variograms for 45, 90, and 135 degrees, omitting 0 degrees (pi/4, pi/2, 3pi/4, omitting 0). If I specify 0 degrees, it returns a variogram with (binned) distances of 1, 2, 3, and 4.
Any ideas what I am doing wrong, or what other information I could provide to better elucidate my problem?
Many thanks, as usual.
