eol_invasive_data(...)

Arguments

name

A taxonomic name, or a vector of names.

dataset

One of all, gisd100, gisd, isc, daisie, i3n, or mineps. See the Details for what each dataset ID.

searchby

One of 'grep' (exact match) or 'agrep' (fuzzy match)

page

A maximum of 30 results are returned per page. This parameter allows you to fetch more pages of results if there are more than 30 matches (Default: 1)

per_page

Results to get per page. Default: 500

key

Your EOL API key; loads from .Rprofile.

messages

(logical) If TRUE the actual taxon queried is printed on the console.

count

(logical) If TRUE, give back a count of number of taxa listed as invasive, if FALSE (default), the normal output is given.

...

curl options passed on to HttpClient

Value

A list of data.frame's/strings with results, with each element named by the input elements to the name parameter.

Details

eol_invasive_data() gives you the entire data.frame from the "dataset=all", while eol() let's you search on a vector of names against any of the datasets

IMPORTANT: note that setting dataset="all" will give you surprising results. EOL does not include informaiton on which of the invasive datasets (i.e., gisd100, gisd, isc, daisie, i3n, or mineps) the taxon is found in, and sometimes e.g., if taxon X is in GISD, you might not find it in "all", weird. I don't know why that's happening, but it shouldn't happen.

IMPORTANT: When you get a returned NaN for a taxon, that means it's not on the invasive list in question. If the taxon is found, a taxon identifier is returned.

Beware that some datasets are quite large, and may take 30 sec to a minute to pull down all data before we can search for your species. Note there is no parameter in this API method for searching by taxon name.

eol() is vectorized, so you can pass a single name or a vector of names.

It's possible to return JSON or XML with the EOL API. However, this function only returns JSON.
