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

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
