Relevant locations have at least two observations in different cycle. Relevant periods have average numbers of at least 15% of the most important period.

Usage

select_relevant(
  observation,
  species,
  repo,
  min_observation = 100,
  min_stratum = 3,
  min_cycle = 2,
  proportion = 0.15
)

Arguments

observation	The dataframe with the visits and location group.
species	The fingerprint of the species.
repo	a git2rdata::repository() object
min_observation	The minimum number of observations for taking a species into account. Defaults to 100.
min_stratum	The required minimum number of relevant locations per stratum. Defaults to 3.
min_cycle	Minimum number of cycles in which a species must be found at a square. Square with sightings from fewer cycles will be ignored. Defaults to 2.
