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, 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 cross-variogram 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 variance-covariances. 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. |

`vario` |
The experimental |
