hi everybody!

i work with variograms. the r-functions i use are:

   
surface<-surf.ls(1,data)                                               
#  Trend Surface
   v<- variogram(surface, nint||)                                        
#  Variogram

nint ist the number of bins used. i interpreted this as the number of 
distance classes (lag). the problem is, my data pairs are minimal 1 
meter apart and maximal 35 meters. if i do a variogram by hand the 
smallest lag i have is 1 meter and i have at most 20 distance classes. 
Only i don't get it detrended by hand. if i do it in r i get it 
detrended nicely but only if i use at least 60 for nint. that is a lot 
though. how come that i have to use 60 bins? what exactly does r do?

thanks a lot!

Anna
