Creates square quadrats aligned on a regular grid

Description

Creates square quadrats aligned on a regular grid

Usage

sampling_grids(
  n_quadrats,
  xmin,
  xmax,
  ymin,
  ymax,
  x0,
  y0,
  delta_x,
  delta_y,
  quadrat_size
)

Arguments

n_quadrats	(integer) Number of sampling quadrats
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.
x0, y0	(numeric value) Lower left corner of the first quadrat in transect and grid sampling
delta_x	(numeric value) Distance between consecutive quadrats in transect and grid sampling in x-direction (the distance between the left sides is measured)
delta_y	(numeric value) Distance between consecutive quadrats in transect and grid sampling in y-direction (the distance between the lower sides is measured)
quadrat_size	(numeric) width of the quadrats.

Value

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