LayeredDAG: Layered Directed Acyclic Graph

Description

Returns the adjacency matrix of a layered Directed Acyclic Graph. In this graph, arrows go from all members of a layer to all members of the following layers. There are no arrows between members of the same layer.

Usage

LayeredDAG(layers, n_manifest = NULL)

Value

The adjacency matrix of the layered Directed Acyclic Graph.

Arguments

layers

list of vectors. Each vector in the list corresponds to a layer. There are as many layers as items in the list. Alternatively, this argument can be a vector of the number of variables per layer.

n_manifest

vector of the number of manifest (observed) variables measuring each of the latent variables. If n_manifest is provided, the variables defined in argument layers are considered latent. All entries of n_manifest must be strictly positive.

Examples

# Example with 3 layers specified in a list
layers <- list(
  c("x1", "x2", "x3"),
  c("x4", "x5"),
  c("x6", "x7", "x8")
)
dag <- LayeredDAG(layers)
plot(dag)

# Example with 3 layers specified in a vector
dag <- LayeredDAG(layers = c(3, 2, 3))
plot(dag)
