All agents?

Report TRUE if all agents have their variable equal to a given value, report FALSE otherwise.

NLall(agents, world, var, val)

# S4 method for matrix,worldMatrix,missing
NLall(agents, world, val)

# S4 method for matrix,worldArray,character
NLall(agents, world, var, val)

# S4 method for agentMatrix,missing,character
NLall(agents, var, val)

Arguments

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.
world	WorldMatrix or worldArray object.
var	Character. The name of the selected agents variable. If agents are patches and the world is a worldMatrix object, var must not be provided. If agents are patches and the world is a worldArray object, var is the name of the layer to use to define the patches values. If agents are turtles, var is one of the turtles' variable and can be equal to xcor, ycor, any of the variables created when turtles were created, as well as any variable created using turtlesOwn().
val	Numeric or character. Vector of any length.

Value

Logical. TRUE if all the agents have their variable equal to val, FALSE otherwise.

Details

world must not be provided if agents are turtles.

Examples

# Patches
w1 <- createWorld(minPxcor = 0, maxPxcor = 4, minPycor = 0, maxPycor = 4, data = runif(25))
NLall(agents = patches(w1), world = w1, val = 5)
#> [1] FALSE
w2 <- w1
w2 <- NLset(world = w1, agents = patches(w1), val = 5)
NLall(agents = patches(w2), world = w2, val = 5)
#> [1] TRUE

# Turtles
t1 <- createTurtles(n = 5, coords = cbind(xcor = 1, ycor = 1), heading = c(1, 2, 2, 1, 2))
NLall(agents = t1, var = "xcor", val = 1)
#> [1] TRUE
NLall(agents = t1, var = "heading", val = 2)
#> [1] FALSE
