No taxon_rank information when parsing from NCBI taxonomy

[janstrauss1]

Hi there,

I'm looking up taxonomic data from NCBI taxon IDs that I would like to subsequently filter using taxon_ranks == "species".

Unfortunately, it seems that NCBI taxon rank information is not parsed when using lookup_tax_data?!

Below a reproducible example:

tax_ids <- data.frame(ID = c("9606","10090","4932"))

taxmap <- lookup_tax_data(
  tax_data = tax_ids,
  type = "taxon_id",
  column = 1,
  datasets = list(),
  mappings = c(),
  database = "ncbi",
  include_tax_data = TRUE,
  use_database_ids = TRUE,
  ask = TRUE
)

Calling taxon_ranks(taxmap) returns

> taxon_ranks(taxmap)

How could I get the taxon rank information from NCBI? Many thanks in advance for your help!
