Calculate Grade-Tonnage curves from estimated Q and T variables

selectivity.qt(db, tnames = NA, qnames = NA, cuts = NA, cells = NA, verbose=0, flag.plot = TRUE, ...)

`db` |
The |

`tnames` |
Names (or ranks) of the columns containing the set of T variables.
Note that there must the same number of T and Q variables.
For more information see |

`qnames` |
Names (or ranks) of the columns containing the set of Q variables.
Note that there must the same number of T and Q variables.
For more information see |

`cuts` |
Array containing the cutoffs for which calculations must be performed.
If not specified, these cutoffs are generated automatically.
In the case of Selectivity curves calculated from a Model (argument
'x' refers to a Model ( |

`cells` |
List of cells that must be regrouped to produce the Grade-Tonnage curve. If not specified, all the active cells are considered. |

`verbose` |
Verbose flag. If switched ON, the value of the GINI index is printed. |

`flag.plot` |
When TRUE, the result of the Selectivity function is plotted. Otherwise, the resulting array is produced as output. See Details for more information. |

`...` |
Arguments passed to the function |

An array of the recovery functions. The number of rows corresponds to the number of cutoffs. There are five columns organized as follows:

1 Cutoff value

2 Tonnage

3 Metal Quantity

4 Conventional Benefit

5 Average recovered grade
