Report the agents
within the "cone of vision" in front of each one of the
turtles
.

turtles 


radius  Numeric. Vector of distances from 
angle  Numeric. Vector of angles to define the size of the cone of vision
for the 
agents  Matrix (

world 

torus  Logical to determine if the 
Matrix (ncol
= 3) with the first column pxcor
and the second column pycor
representing the coordinates of the
patches
among agents2
within the cone of vision of each of the
turtles
which are represented by the id
column, if
agents
are patches
, or
Matrix (ncol
= 2) with the first column who
representing the who
numbers of the
turtles
among agents2
within the cone of vision of each of the
turtles
which are represented by the id
column, if
agents
are turtles
.
agents
are reported if there are within radius
distance of the turtle
and their direction from the turtle
is within
[angle, + angle]
of the turtle
's heading.
Distances to patches
are calculated to their center.
If torus = FALSE
, world
does not need to be provided.
If torus = TRUE
, the radius
distances are calculated
around the sides of the world
to select agents
