| get.grid.sorting {RGeostats} | R Documentation |
Returns your grid indices in Geoslib order
get.grid.sorting(nx, order = 0, verbose = FALSE)
nx |
Array of grid dimensions. It fixes the dimension of the space and the total number of grid cells ('ncell') |
order |
Array giving your grid order (See details) |
verbose |
Verbose flag |
The idea is to provide the rank of the indices (for the internal sorting method within Geoslib) for an external array that would be defined in another way. Say that you have an array (defined in dimension 3) with 2 positions along the first axis, 3 along the second index and 4 along the third index.
-> nx = c(2,3,4)
Let us imagine that the values are sorted by increasing first index (internal loop) followed by a decreasing third index and finally an increasing second index.
-> order = "+x1-x3+x2"
This function returns an array 'tab' of indices (Dimension: ncell). For sample #i, tab[i] gives the position that the sample should have in the Geoslib grid organization
