Helper generic function for obtaining the anthropometric cases

Description

Because the goal of the methodologies included in this package is always to estimate a number of anthropometric cases given a data set (both central (prototypes) and boundaries (archetypoids)), this auxiliary generic function allows the user to identify the cases computed by each method in an easy way.

Usage

anthrCases(resMethod, nsizes)
## S3 method for class 'trimowa'
 anthrCases(resMethod, nsizes)
## S3 method for class 'hipamAnthropom'
 anthrCases(resMethod, nsizes)

Arguments

resMethod	This is the object which saves the results obtained by the methodologies and which contains the anthropometric cases to return.
nsizes	Number of bust sizes. This argument is needed for the "trimowa" and "hipamAnthropom" methodologies because they can compute the prototypes for any given number of bust sizes.

Value

A vector of class anthrCases with the anthropometric cases.
