Report the distances between agents
and agents2
.
NLdist(agents, agents2, world, torus = FALSE, allPairs = FALSE) # S4 method for matrix,matrix NLdist(agents, agents2, world, torus = FALSE, allPairs = FALSE)
agents  Matrix (ncol = 2) with the first column "pxcor" and the second column "pycor" representing the patches coordinates, or AgentMatrix object representing the moving agents. 

agents2  Matrix (ncol = 2) with the first column "pxcor" and the second column "pycor" representing the patches coordinates, or AgentMatrix object representing the moving agents, or Matrix (ncol = 2) with the first column "x and the second column "y" representing locations coordinates. 
world  WorldMatrix or worldArray object. 
torus  Logical to determine if the 
allPairs  Logical. Only relevant if the number of agents/locations in

Numeric. Vector of distances between agents
and agents2
if
agents
and/or agents2
contained
one agent/location, or if agents
and agents2
contained the same
number of agents/locations and allPairs = FALSE
, or
Matrix of distances between agents
(rows) and
agents2
(columns)
if agents
and agents2
are of different lengths,
or of same length
and allPairs = TRUE
.
Distances from/to a patch are measured from/to its center.
If torus = FALSE
, world
does not need to be provided.
If torus = TRUE
, a distance around the sides of the world
is
reported only if smaller than the one across the world
