refseq_GeneID {refseqR}

Get the GeneID

Description

refseq_GeneID() Returns the GeneID from a single transcript or 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_GeneID (accession, db, retries)

Arguments

accession

A character string of the transcript or protein accession.

db

A character string of the "nuccore" or "protein" database.

retries

A numeric value to control the number of retry attempts to handle internet errors.

Value

A character vector containing the GeneID corresponding to the specified accession as accession.
