Report the coordinates of the patches
at the given
distances and directions from the agents
.
patchDistDir(world, agents, dist, angle, torus = FALSE)
# S4 method for worldNLR,matrix,numeric,numeric
patchDistDir(world, agents, dist, angle, torus = FALSE)
WorldMatrix
or worldArray
object.
Matrix (ncol
= 2) with the first column pxcor
and the second
column pycor
representing the patches
coordinates, or
Numeric. Vector of distances from the agents
. Must be
of length 1 or of the same length as the number of agents
.
Numeric. Absolute directions from the agents
. angle
must be of length 1 or of the same length as the number of
agents
. Angles are in degrees with 0 being North.
Logical to determine if the world
is wrapped. Default is
torus = FALSE
.
Matrix (ncol
= 2) with the first column pxcor
and the second column
pycor
representing the coordinates of the patches
at the distances
dist
and directions angle
of agents
.
The order of the patches
follows the order of the agents
.
If torus = FALSE
and the patch
at distance dist
and
direction angle
of an agent
is outside the world
's extent,
NA
are returned for the patch
coordinates.
If torus = TRUE
, the patch
coordinates from a wrapped world
are returned.
