order

order

Ordinal numbers to cells in ascending order

Result = order(expression)
expression
spatial scalar, ordinal
Result
spatial scalar

Operation

Let n be the number of non missing value cells on expression. These cell values are set in order and numbered on Result in ascending order: the cell with the smallest value on expression is assigned a 1 and the cell with the largest value is assigned a number n. Cells on expression with identical values are assigned consecutive, unique numbers; the order in which these cells are numbered is arbitrarily chosen.

Notes

A cell with missing value on expression is not considered in the order operation; it is assigned a missing value on Result.

Group

This operation belongs to the group of Order

Examples

  1. • pcrcalc
    binding
    Result = Result.map;
    Expr = Expr.map;
    initial
    report Result = order(Expr);

    • python
    Expr = readmap(“Expr.map”)
    Result = order(Expr)
    Result.map Expr.map
