Get number of points within varying distances

Usage

lg_points(
  x,
  y,
  dist_seq = NULL,
  bound_poly = NULL,
  mindist = NULL,
  maxdist = NULL,
  incdist = NULL
)

Arguments

x: The measurement points
y: The points to be summed
dist_seq: The sequence of distance values
bound_poly: Optional polygon to be kept within
mindist: The minimum distance, ignored if dist_seq is specified
maxdist: The maximum distance, ignored if dist_seq is specified
incdist: The distance increment, ignored if dist_seq is specified

Value

list containing matrices of the number of points (buffer_values), buffer area (buffer_area) and average number of points per unit area (value_parea) for every distance increment. All matrices will have number of rows equal to the number of measurement points unless bound_poly = NULL in which case buffer_area and points_parea will be returned as NA.
