Get the amino acid length from a protein accession

Description

refseq_AAlen() Returns the amino acid length from a single protein accession.

Depending on the function, available accessions in refseqR include RefSeq models with the prefixes XM_ (mRNA), XR_ (non-coding RNA), and XP_ (protein), as well as subsequently curated RefSeq records with NM_, NR_, or NP_ accession prefixes.

Usage

refseq_AAlen(protein)

Arguments

protein

A character string of the protein id.

Value

A numeric value representing the aa length of the protein.
