This argument can be either:

• The anam-class Class containing the Anamorphosis characteristics

• A db-class object containing the target variables

• A vector of numeric values

Vector containing the (optional) weight. This vector will be used only when 'x' is provided as a vector numeric values. When 'x' corresponds to a db-class, the (optional) weight is provided by a (locator "w") variable.

When the argument 'x' corresponds to a db-class object, the name of the variable of interest can be given. By default, this variable will be the one with locator "z1".

When the argument 'x' corresponds to a db-class object, the name of the weight variable can be given. By default, this variable will be the one with locator "w".

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 (anam-class), and if the Model is Discrete, then the cutoffs are the ones of the Model and the current argument is useless (they do not need to be defined explicitely as they will be generated automatically by the program).

When the cutoffs are generated automatically, this argument specifies the number of discretized cutoffs between the minimum and the maximum.

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

When TRUE, the Tonnages are corrected in order to ensure the order relationship before calculating other quantities.

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