Language issue when posting

If I post this text as an answer, I get an error that I have to use English instead of [nl]. Whatever language [nl] might be. There is no hint as to what word is being interpreted as being non-English.


```
> library(biomaRt)
> mart <- useEnsembl("ensembl","hsapiens_gene_ensembl")


> getBM("ensembl_gene_id","entrezgene_id", "1", mart)
  ensembl_gene_id
1 ENSG00000121410

```
