R: Missing Allelic Data

na.omit.loci {pegas} | R Documentation

## Missing Allelic Data

### Description

This is a method of the generic function `na.omit`.

### Usage

    ## S3 method for class 'loci'
    na.omit(object, na.alleles = c("0", "."), ...)

### Arguments

`object` | an object of class `"loci"`.
`na.alleles` | a vector of charater strings giving the alleles to be treated as missing data.
`...` | (unused)

### Details

The side effect of this function is to drop the rows (individuals) with unclearly identified genotypes, i.e., with at least one allele among `na.alleles`.

Other variables in the data table are eventually checked and levels with no observation (e.g., population) are dropped.

### Value

an object of class `"loci"`.
