I cannot access the zebra fish ensembl database with biomaRt in R...
# biomaRt library (biomaRt) listMarts() ensembl <- useMart("ensembl") listDatasets(ensembl) #output is really bad, with huge spaces between lines (cannot copy it here) listDatasets(ensembl)$dataset
Can't see the zebra fish dataset in the list!
ensembl = useDataset("drerio_gene_ensembl", mart = ensembl)
Error in useDataset("drerio_gene_ensembl", mart = ensembl) : The given dataset: drerio_gene_ensembl , is not valid. Correct dataset names can be obtained with the listDatasets function.
While it looks like the correct name (I'm following a tutorial)... What is happening?
