Dear list,

 

When plotting directional variograms, I wonder why in the first plot I see a
different sample variogram for the 45 direction than in the second plot
(where I only want to plot the 45° variogram). Do I have to define for the
second plot an angular tolerance that is default for the first plot? 

 

dir.lz <- variogram(log(zinc)~1, data=meuse, alpha=c(0,45,90,135),
cutoff=1800, width=200)

plot(dir.lz)

 

dir45.lz <- variogram(log(zinc)~1, data=meuse, alpha=c(45), cutoff=1800,
width=200)

plot(dir45.lz)

 

Thank you for any suggestion.
