Report TRUE
if the agents
is of the class
tested,
report FALSE
otherwise.
isNLclass(agents, class)
# S4 method for matrix,character
isNLclass(agents, class)
Matrix (ncol
= 2) with the first column pxcor
and the second
column pycor
representing the patches
coordinates, or
Character. Can take one of the following options to define
the class
: "agent"
, "agentset"
,
"patch"
, "patchset"
. "turtle"
or "turtleset"
.
Logical. TRUE
if agents
is of the class
tested.
Careful! The class
tested does not correspond to actual R classes.
`agents` is `"patch"` if it is a matrix (`ncol` = 2) with the
first column `pxcor` and the second column `pycor` with only
one row. `agents` is `"patcheset"` if the matrix has more than
one row.
`agents` is `"turtle"` if it is an `agentMatrix`
containing only one `turtle`.
`agents` is `"turtleset"` if the
`agentMatrix` contains more than one `turtle`.
`agents` is `"agent"` if it is either `"patch"` or
`"turtle"`. `agents` is `"agentset"` if it is either
`"patcheset"` or `"turtleset"`.
