### Arguments

`...` | For `classification`: other arguments passed to `get_tsn`, `get_uid`, `get_eolid`, `get_colid`, `get_tpsid`, `get_gbifid`, `get_wormsid`, `get_natservid`, `get_wormsid`, `get_wiki`. For `rbind.classification` and `cbind.classification`: one or more objects of class `classification`
`x` | Vector of taxa names (character) or IDs (character or numeric) to query.
`db` | character; database to query. either `ncbi`, `itis`, `eol`, `col`, `tropicos`, `gbif`, `nbn`, `worms`, `natserv`, `bold`, or `wiki`. Note that each taxonomic data source has, their own identifiers, so that if you provide the wrong `db` value for the identifier you could get a result, but it will likely be wrong (not what you were expecting).
`callopts` | Curl options passed on to `GET`
`return_id` | (logical) If `TRUE` (default), return the taxon id as well as the name and rank of taxa in the lineage returned. Ignored for natserv as they don't return IDs in their taxonomic classification data.
`rows` | (numeric) Any number from 1 to infinity. If the default NA, all rows are considered. Note that this parameter is ignored if you pass in a taxonomic id instead of a name of class character.
`id` | character; identifiers, returned by `get_tsn`, `get_uid`, `get_eolid`, `get_colid`, `get_tpsid`, `get_gbifid`, `get_tolid`, `get_wormsid`, `get_natservid`, `get_wormsid`, `get_wiki`
`key` | Your API key; loads from .Rprofile.
`start` | The first record to return. If omitted, the results are returned from the first record (start=0). This is useful if the total number of results is larger than the maximum number of results returned by a single Web service query (currently the maximum number of results returned by a single query is 500 for terse queries and 50 for full queries).
`checklist` | character; The year of the checklist to query, if you want a specific year's checklist instead of the lastest as default (numeric).

### Details

If IDs are supplied directly (not from the `get_*` functions) you must specify the type of ID. There is a timeout of 1/3 seconds between queries to NCBI.

BEWARE: Right now, NBN doesn't return the queried taxon in the classification. But you can attach it yourself quite easily of course. This behavior is different from the other data sources.

### Value

A named list of data.frames with the taxonomic classification of every supplied taxa.

### Lots of results

It may happen sometimes that you get more results back from your query than will show in the data.frame on screen. Our advice is to refine your query in those cases. On a data source basis we can attempt to help make it easier to refine queries, whether it be with the data provider (unlikely to happen), or in the code in this package (more likely) - let us know if you run into too many results problem and we'll see what we can do.
