[R] determination of the number of lags

[CELINE RONDEY]

Dear all,

I wish use the "est.variogram" function under R.
My question concerns the determination of number of lags.

To make this calculation, i determined the biggest and the smallest
distance between 2 pairs of points.
I built the following tolerance : tol=mindistance/2 and i defined 1 lag as
: 1lag=mindist+tol.
Then i made a buckle the step of stop of which the maximal distance.
But, i don't known if this method is correct.

So, my question is :
How to determine num.lag correctly?


Thanks in advance for all kind of help.
