DAG | R Documentation |

This function is a simple wrapper around the function from the `ggm`

package with the same name. The only differences are that the `order`

argument defaults to `TRUE`

and that it adds a `DAG`

class for
easy plotting. Typically, one would use `define_model_set()`

to
create models for use with the `phylopath`

package.

```
DAG(..., order = TRUE)
```

`...` |
a sequence of model formulae |

`order` |
logical, defaulting to |

Supply a formulas for the model as arguments. Formulas should be of the
form `child ~ parent`` and describe each path in your model. Multiple children of a single parent can be combined into a single formula: `

child ~ parent1 + parent2`. Finally, an isolate (unconnected variable) can be included as being connected to itself: `

isolate ~ isolate'.

An object of classes `matrix`

and `DAG`

```
# Use formula notation to create DAGs:
plot(DAG(A~B, B~C))
# Use + to easily add multiple parents to a node:
plot(DAG(A~B+C))
# Add a node as it's own parent to create an isolate:
plot(DAG(A~B+C, D~D))
```
