When requesting data using finbif you can select from among (or order by) many variables (properties of the occurrence records). The default set of variables returned is a small subset of those available. Note that not all variables are available for all records. See ?variables for details.

Selecting variables

Limiting variables

To retrieve a limited set of variables from FinBIF simply specify the desired variables in the select argument.

finbif_occurrence(
  genus  = "Falco",
  select = c("scientific_name", "life_stage", "sex")
)

Ordering

You can change the order of occurrence records before they are fetched from the server by using the order_by argument. The default ordering is date_start descending, then load_date descending, then reported_name.

Ascending order

By default occurrence records are ordered by variables in ascending order.
