Error/Warning readability is low:

> OMneuro_CoSIAn_biomart <- CoSIA::getConversions(OMneuro_CoSIAn_biomart)
Warning: One or more gene input gene ID/cluster not found in homologue tableWarning: One or more gene ID/cluster with no target provided in homologue tableJoining, by = "h_sapiens_entrez_id"Warning: No orthologs were found for m_musculus across all the genes provided by the user.

Suggesting to change this:

> message("Joining, by = \"h_sapiens_entrez_id\"Warning: No orthologs were found for m_musculus across all the genes provided by the user.")
Joining, by = "h_sapiens_entrez_id"Warning: No orthologs were found for m_musculus across all the genes provided by the user.

To this:

> message("Joining, by = \"h_sapiens_entrez_id\"\nWarning: No orthologs were found for m_musculus across all the genes provided by the user.\n")
Joining, by = "h_sapiens_entrez_id"
Warning: No orthologs were found for m_musculus across all the genes provided by the user.
