Hi,

I want to access an archived version of biomart and select the human dataset.

mart=useMart("ensembl_mart_92",host="http://apr2018.archive.ensembl.org")

works but if I do:

mart=useMart("ensembl_mart_92",host="http://apr2018.archive.ensembl.org", dataset = "hsapiens_gene_ensembl")

it gives error:

Error in checkDataset(dataset = dataset, mart = mart) : 
  The given dataset:  hsapiens_gene_ensembl , is not valid.  Correct dataset names can be obtained with the listDatasets() function.

If I look into listDatasets() as suggested I get:

mart=useMart("ensembl_mart_92",host="http://apr2018.archive.ensembl.org")
listDatasets(mart)
[1] dataset     description version    
<0 rows> (or 0-length row.names)

Also tried other suggestions online that didn't work:

listMarts(archive = TRUE)

Error in listMarts(archive = TRUE) : 
The archive = TRUE argument is now defunct.
Use listEnsemblArchives() to find the URL to directly query an Ensembl archive.
