Thomas process individual distribution simulation for one species

Description

Usually used internally inside sim_thomas_coords This function randomly draws points (individuals) around one or several mother points using Rcpp. The function is an efficient re-implementation of the rThomas function from the spatstat package.

Arguments

n_points	The total number of points (individuals).
n_mother_points	Number of mother points (= cluster centres).
xmother	Vector of n_mother_points x coordinates for the mother points.
ymother	Vector of n_mother_points y coordinates for the mother points.
sigma	Mean displacement (along each coordinate axes) of a point from its mother point (= cluster centre).
xmin	Left limit, default=0.
xmax	Right limit, default=1.
ymin	Bottom limit, default=0.
ymax	Top limit, default=1.

Value

A dataframe with x and y coordinates.
