我无法在R ...中使用biomaRt访问斑马鱼ensembl数据库。
# 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
返回

斑马鱼数据库在哪里？
ensembl = useDataset("drerio_gene_ensembl", mart = ensembl)
返回：
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.
虽然它看起来像是正确的名字（我在教程之后）......发生了什么事？
