How to make common social science diagrams using DiagrammeR

The DiagrammeR package is great for programmatically creating diagrams using the GraphViz language.

However, it can be challenging to figure out how to create common graphs using GraphViz. Therefore, I compiled a list of some common graphs and plots to get you started.

Concepts

Display hierarchies and relationships between theoretical constructs.

Hierarchy of concepts

Experiments

Randomization procedure.

Randomized control trial, experiment and control group

2 x 3 factorial experiment with pre-test and post-test

Causal diagrams

Variables and relationships, directed acyclic graphs (DAG's) etc.

Cause and effect (2 variables)

Cause, mediator and effect (3 variables)

Cause, moderator and effect (3 variables)

Partial mediation with 1 mediator (3 variables)

Partial mediation with 2 mediators (4 variables)

Structural equation models

Latent factors and their indicators etc.

Moderated mediation with latent factor

Meta-analysis

Flowcharts for inclusion and exclusion of studies.
