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
