isPoly-methods {adegenet}

Assess polymorphism in genind/genpop objects

Description

The simple function isPoly can be used to check which loci are polymorphic, or alternatively to check which alleles give rise to polymorphism.

Usage

## S4 method for signature 'genind'
isPoly(x, by=c("locus","allele"), thres=1/100)
## S4 method for signature 'genpop'
isPoly(x, by=c("locus","allele"), thres=1/100)

Arguments

x

a genind and genpop object

by

a character being "locus" or "allele", indicating whether results should indicate polymorphic loci ("locus"), or alleles giving rise to polymorphism ("allele").

thres

a numeric value giving the minimum frequency of an allele giving rise to polymorphism (defaults to 0.01).

Value

A vector of logicals.
