Report n patches or turtles randomly selected among agents.
nOf(agents, n)
# S4 method for matrix,numeric
nOf(agents, n)Matrix (ncol = 2) with the first column pxcor and the second
column pycor representing the patches coordinates, or
Matrix (ncol = 3) with the first column "pxcor and the second
column pycor representing the patches coordinates and the
third column id, or
AgentMatrix object representing the moving agents, or
Matrix (ncol = 2) with the first column whoTurtles and the
second column id.
Integer. Number of patches or turtles to select from agents.
Matrix (ncol = 2, nrow = n) with the first column pxcor and the second column pycor representing the coordinates of the
selected patches from agents, or
Matrix (ncol = 2) with the first column pxcor and the second column pycor representing the coordinates of the
selected patches from agents, n per individual "id", or
AgentMatrix (nrow = n) representing the turtles selected from agents,
Integer. Vector of who numbers for the selected turtles from
agents, n per individual "id".
n must be less or equal the number of patches
or turtles in agents.
If agents is a matrix with ncol = 3, the selection of n
random patches is done per individual "id". The order of the patches
coordinates returned follow the order of "id".
If agents is a matrix (ncol = 2) with columns whoTurtles and
id, the selection of n random turtles (defined by their whoTurtles)
is done per individual "id". The order of the who numbers returned
follow the order of "id".
