DAG

Directed Acyclic Graph with labeled nodes. This structure is a very thin wrapper around SimpleDiGraph from LightGraphs package.

Dagitty.DAG — Type
DAG

Structure with fields:

  • graph::SimpleDiGraph - underlying directed graph
  • labels::Vector{Symbol} - vector of each nodes' label

Could be constructed by passing list of Pair{Symbol, Symbol}

Examples

julia> using Dagitty

julia> g = DAG(:A => :B)
DAG: {2, 1} directed simple Int64 graph with labels [:A, :B])

julia> g.graph
{2, 1} directed simple Int64 graph

julia> g.labels
2-element Vector{Symbol}:
 :A
 :B

julia> g = DAG(:A => :A)
ERROR: DAGHasLoops()
source
Dagitty.DAGHasLoops — Type
DAGHasLoops

Exception, thrown when loops are detected on DAG construction.

Examples

julia> using Dagitty

julia> g = DAG(:A => :B, :B => :A)
ERROR: DAGHasLoops()
source
Dagitty.LabelNotFound — Type
LabelNotFound

Exception thrown on attempt to resolve label which is not present in the DAG.

Examples

```jldoctest julia> using Dagitty

julia> g = DAG(:A => :B) DAG: {2, 1} directed simple Int64 graph with labels [:A, :B])

julia> node(g, :C)
