DNA.dist {QSutils} | R Documentation

## Matrix of DNA distances given an alignment

### Description

Function to compute a matrix of pairwise distances from DNA sequences using a model of DNA evolution. It relies on the `dist.dna()` function in the APE package.

### Usage

    DNA.dist(seqs, model = "raw", gamma = FALSE, pairwise.deletion = FALSE)

### Arguments

`seqs` | DNAStringSet object with the aligned haplotypes.
`model` | Evolutionary model to compute genetic distance by default "raw", but "N", "TS", "TV", "JC69", "K80", "F81", "K81", "F84", "BH87", "T92","TN93", "GG95", "logdet", "paralin", "indel", or "indelblock" can also be used.
`gamma` | Gamma parameter possibly used to apply a correction to the distances or FALSE (by default).
`pairwise.deletion` | A logical indicating whether to delete sites with missing data (gaps) in a pairwise manner. The default is to delete sites with at least one missing datum in all sequences.

### Value

Object of class "dist" with pairwise distances.
