nOf.RdReport n patches or turtles randomly selected among agents.
nOf(agents, n) # S4 method for matrix,numeric nOf(agents, n)
| agents | 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". |
|---|---|
| n | Integer. Number of patches or turtles to select from |
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".
