In FelixMay/MoBspatial: Spatial Simulation and Scale-Dependent Analysis of Biodiversity Changes

Creates coordinates (lower left corner of a quadrat) randomly distributed but without overlapping each other

Description

Efficient algorithm from package spatstat.random is used. Produces similar results as sampling_random_bruteforce.

Usage

sampling_random_spatstat(
  n_quadrats,
  min_dist,
  xmin,
  xmax,
  ymin,
  ymax,
  seed = NULL
)

Arguments

n_quadrats	Number of sampling quadrats
min_dist	(numeric) minimal distance between two points to avoid overlap. Equal to the length of a quadrat diagonal
xmin	(numeric) minimum possible value on the x axis a quadrat can cover.
xmax	(numeric) maximum possible value on the x axis a quadrat can cover.
ymin	(numeric) minimum possible value on the y axis a quadrat can cover.
ymax	(numeric) maximum possible value on the y axis a quadrat can cover.
seed	(integer) Any integer passed to set.seed for reproducibility.

Value

a data.frame with 2 columns x and y giving the coordinates of the lower left corner of the square quadrats.
