vario.vect {RGeostats}  R Documentation 
Compute noncentered covariance for directional variable.
vario.vect(db, ncomp=3, dirvect = NA, lag = NA, toldis = 0.5, tolang = NA, bench=0, cylrad=0, nlag = NA, opt.code=0, tolcode=0, means=NA, vario.add=NA)
db 
The 
ncomp 
Number of components. The number of variables of the Db must be a multiple of the number of components: the number of variables for the variogram calculation is obtained as the ratio of the number of variables of the DB by the number of components 
dirvect 
The directions in which the variogram must be calculated.
For more information, refer to 
lag 
Array containing the distance lags for each calculation direction. If no corresponding lag is not defined, a default lag is calculated so that the maximum distance is equal to half of the field diagonal. For one distance, if the lag is not defined, it is set to the default lag. 
toldis 
Tolerance on the distance, expressed as a percentage of the lag. 
tolang 
Array containing the angular tolerance for each calculation direction. If no angular tolerance is not defined, a default tolerance is calculated as one half of the angle. For one direction, if the angular tolerance is not defined, it is set to the default tolerance. 
bench 
Array containing the bench separation tolerance for each calculation direction. When bench is defined and positive, a pair is discarded if the separation distance between the two points along the third axis is larger than 'bench'. 
cylrad 
Array containing the cylrad tolerance for each calculation direction. When specified and positive, a pair is discarded if the separation distance in the plane orthogonal to the calculation distance is larger than 'cylrad'. 
nlag 
Array containing the number of lags for each calculation direction. If not defined, the defaulted number of lags is set to 10. For one direction, if the number of lags is not defined, it is set to 10. 
opt.code 
Array containing the option concerning the use of the code for each direction. This option defines the strategy for the code usage when considering a pair of samples:

tolcode 
Array giving the maximum distance between the codes of the two samples for each direction. 
means 
Array corresponding to the estimated means of the variable using for the Poisson variogram calculation 
vario.add 
When defined, the current variogram computation is concatenated to the contents of the current variogram. 
An experimental varioclass
