R help - Sep 2004 - geoR/variog4() not returning all directions

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.

Hi Martin

The only pssible explanation I can find from your description is that the
code may not be fiuding pairs in one of the directions.

however...I never discard the possibility of a bug :)

Could you please send me the data and the piec of relevant code such that
i can rteproduce the error here?

Thanks
P.J,
