Dear Benjamin,
I can't see what's wrong with your query, but it looks like the issue is coming
from the following attributes:
"mmusculus_homolog_orthology_type"
"mmusculus_homolog_subtype"
"mmusculus_homolog_perc_id"
If you do the following query you will get the same error back:
> library(biomaRt)
> human = useMart("ensembl", dataset = "hsapiens_gene_ensembl")
> attributes =
> c("ensembl_gene_id","mmusculus_homolog_ensembl_gene","mmusculus_homolog_orthology_type")
> orth.mouse = getBM(attributes, filters="with_homolog_mmus",values=TRUE, mart
> = human, uniqueRows=TRUE)this might be a bug coming from the biomaRt package.

Error in `[.data.frame`(result, , attributes) :
undefined columns selected
It's when you start adding one of the previous attribute that the query fail.
I have also try your query with the host pointing to ensembl.org and I am
getting the same error.
Since the query is working fine on the biomart interface, this might be a bug
coming from the biomaRt package. I would advise you to email the bioconductor
list: [email protected]
Hope this helps,
Regards,
Thomas
