vario.create {RGeostats}  R Documentation 
Create or append a variogram from arguments
vario.create(lag, gg, hh = NA, sw = NA, nvar = 1, ndim = 2, toldis = 0, tolang = 0, bench=0, cylrad=0, codir = NA, mean = NA, vars = NA, dates=NA, vario = NA)
lag 
Lag value used for the calculation. The number of lags is derived from the dimension of the array 'gg' divided by nvs2=nvar*(nvar+1)/2. 
gg 
Array containing the variogram value per class 
hh 
Array containing the variogram average distances per class. If this array is not provided, it is established as a multiple of the lag 
sw 
Array containing the variogram weight per class (usually refers to the number of pairs). If not provided, this array is constantly set to 1. 
nvar 
Number of variables. If nvar>1, the arrays are assumed to give consecutively, the 'nlag' values of the simple variogram of variable 1, followed by the 'nlag'values of the crossvariogram of variables 1 and 2, ... If this function is used in append mode, the number of variables in the original variogram prevails. 
ndim 
Space dimension. If this function is used in append mode, the space dimension in the original variogram prevails. 
toldis 
Tolerance on distance used for calculations 
tolang 
Tolerance on direction used for calculations 
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'. 
codir 
Direction coefficients. If not provided, the default if the unit vector in the first direction of the space 
mean 
Array of the means. The dimension of this array should be equal to nvar. If not provided, it is set constantly to 0. 
vars 
Array of the variancecovariances. The dimension of this array should be equal to nvar*nvar. If not provided, it is set constantly to 1. for the diagonal terms and 0 otherwise. 
dates 
When defined and if the 'time' locator is defined, this value corresponds to the bounds of the Date Intervals. It is organized as follows:
