WebCreating DAGs in R. To create our DAGs in R we will use the ggdag packages. The first thing we will need to do is to create a dagified object. That is an object where we state our variables and the relationships they have to each other. Once we have our dag object we just need to plot with the ggdag () function. Webdirected graph is acyclic if it has no cycles. In this case we say that the graph is a directed acyclic graph or DAG.
