sample_explan_data | R Documentation |
A dataset containing a sample of the bird species, the red-billed quelea (Quelea quelea), distribution records from between 2002-2019 (GBIF 2021, GBIF 2022); generated pseudo-absence records, and associated extracted dynamic explanatory variables. The variables are as follows:
sample_explan_data
A data frame with 330 rows and 17 variables:
species occurrence record longitude.
species occurrence record latitude.
species occurrence record year.
species occurrence record month.
species occurrence record day.
species occurrence record latitude.
species occurrence record longitude.
species presence or absence character.
source of occurrence or pseudo-absence data point.
name of species occurrence records belong to name
total number of avian e-Bird sampling events within spatiotemporal buffer of occurrence record location and dates.
proportion of total number of avian e-Bird sampling events within spatiotemporal buffer of occurrence record location and dates relative to other records
unique id value assigned when extracting dynamic explanatory variable data
