vardir-class {RGeoS} | R Documentation |
This class contains an experimental variogram calculated in one direction for one or several variables.
Objects can be created by calls of the form new("vardir", ...)
.
Elementary experimental variogram
npas
:Object of class "numeric"
Number of lags
npatot
:Object of class "integer"
Total number of lags
pas
:Object of class "numeric"
Lag value
tol
:Object of class "numeric"
Tolerance on distance (as percentage of lag value)
flag.regular
:Object of class "numeric"
Specify if regular lags must be considered
breaks
:Object of class "numeric"
Array of irregular lags
codir
:Object of class "numeric"
Vector of direction coefficients
size
:Object of class "integer"
Total dimension of variogram arrays
sw
:Object of class "numeric"
Array of weights
hh
:Object of class "numeric"
Array of distances
gg
:Object of class "numeric"
Array of variogram values
vardir[ivar,jvar,ipas]
returns the list (sw,gg,hh) corresponding to the arrays of weights, variogram values and distances for the lag ipas
and the pair of variables ivar
and jvar
.
Same but for assignment
vardir$parameter
is used to query the value of parameter
from vardir
:
npas : Number of lags
npatot : Total number of lags (=npas for symmetric function and =2*npas for asymetric functions)
pas : Lag
tol : Tolerance on the distance (as a percentage of the lag)
flag.regular : 1 for regular lags and 0 otherwise
breaks : Array of irregular lags (if flag.regular=0)
codir : Vector of direction coefficients
size : Total dimension of the variogram arrays
sw : Array containing the variogram weights
gg : Array containing the variogram values
hh : Array containing the variogram distances
Same but for assignment
