  A matrix of character, each element is a single-character symbol for a amino acid.

`upstreamOffset`

`downstreamOffset`

  An integer, the downstream offset relative to the anchoring position.

`type`

  A character vector of length 1. Available options :"UniProt", and "fasta" if the `dagPeptides` object is generated using the function `formatSequence`, or "entrezgene" and "uniprotswissprot" if generated by the function `fetchSequence`.

### Objects from the Class

Objects can be created by calls of the form

`new("dagPeptides", data, peptides, upstreamOffset, downstreamOffset, type)`.
