adegenet (version 1.2-6)

genind class: adegenet formal class (S4) for individual genotypes

Description

The S4 class genind is used to store individual genotypes. It contains several components described in the 'slots' section). The summary of a genind object invisibly returns a list of component. The function .valid.genind is for internal use. The function genind creates a genind object from a valid table of alleles corresponding to the @tab slot. Note that as in other S4 classes, slots are accessed using @ instead of $.
