Dear list:

I have a 5x5 regular grid 100x100. When constructing the experimental semivariogram using gerR() I expected to have 14 different distances.
However, I obtained 10 semivariogram points corresponding to 10 bins. 

- Which is exactly a bin? 
- Which is the bin correspondence wiht the 14 initial distances.
- Why don't the first bin is not exactly 25?
- The dataset is the following.

Thanks in advance,
Gema
