Orthologous gene pairs from Ensembl

Description

Orthologous gene pairs from Ensembl

Usage

ensembl_orthology(
  organism_a = 9606,
  organism_b = 10090,
  attrs_a = NULL,
  attrs_b = NULL,
  colrename = TRUE
)

Arguments

organism_a	Character or integer: organism name or identifier for the left side organism. We query the Ensembl dataset of this organism and add the orthologues of the other organism to it. Ideally this is the organism you translate from.
organism_b	Character or integer: organism name or identifier for the right side organism. We add orthology information of this organism to the gene records of the left side organism.
attrs_a	Further attributes about organism_a genes. Will be simply added to the attributes list.
attrs_b	Further attributes about organism_b genes (orthologues). The available attributes are: "associated_gene_name", "chromosome", "chrom_start", "chrom_end", "wga_coverage", "goc_score", "perc_id_r1", "perc_id", "subtype". Attributes included by default: "ensembl_gene", "ensembl_peptide", "canonical_transcript_protein", "orthology_confidence" and "orthology_type".
colrename	Logical: replace prefixes from organism_b attribute column names, so the returned table always have the same column names, no matter the organism. E.g. for mouse these columns all have the prefix "mmusculus_homolog_", which this option changes to "b_".

Details

Only the records with orthology information are returned. The order of columns is the following: defaults of organism_a, extra attributes of organism_b, defaults of organism_b, extra attributes of organism_b.

Value

A data frame of orthologous gene pairs with gene, transcript and peptide identifiers and confidence values.
