Description |

Vector |
name of vector to rank (see Arrays in functions) |

Direction |
direction of rank (SORT_ASCENDING - rank from smallest to largest value, SORT_DESCENDING - rank from largest to smallest value) |

DupControl |
assignment of ranks to duplicate (identical) values (RANK_FIRST, RANK_LAST, RANK_MEAN) |

The VectorRank function will rank (assign integer values to) the values in Vector (see Arrays in functions), either from the smallest value to the largest value (SORT_ASCENDING), or from the largest value to the smallest value (SORT_DESCENDING). Parameter DupControl determines how identical (duplicated) values in Vector are handled; if DupControl is set to RANK_FIRST, then the smallest possible rank (for the respective set of identical values) is assigned to each duplicate value in Vector; if DupControl is set to RANK_LAST, then the largest possible rank is assigned to each duplicate value in Vector (tied ranks); if DupControl is set to RANK_MEAN, then the average rank for all duplicate values will be assigned to each duplicate value in Vector (tied ranks).
