Filter eBird data for eligible checklists

For various usecases, it is required to filter the eBird dataset and use only "eligible" checklists. An example is the monthly eBird challenges run by various collectives across the world. As such, definitions of "eligibility" tend to vary, but there are two popularly used definitions which can be accessed via the standard argument. On the other hand, it is also possible to create a custom eligibility filter, by setting standard = NULL and providing input to the other arguments.

Usage

filter_eligible(
  data,
  standard = "bci",
  complete = NULL,
  duration = NULL,
  counts = NULL
)
