• Lollipop plot: https://r-graph-gallery.com/lollipop-plot.html

7.4 Multivariate Correlation Matrices

Used for: association between multiple numeric variables

For correlation matrices, I do the following:

1. I use the lab’s cor.table() function (with type = "manuscript") from the petersenlab package to create a correlation matrix.
2. I save the correlation matrix to a .csv file.
   1. For example: https://research-git.uiowa.edu/PetersenLab/SRS/SRS-SelfRegulationDevelopment/-/blob/master/Analyses/selfRegulationDevelopment.Rmd#self-regulation-measures
3. I open the .csv file in Excel and create the table in Excel that can be copied and pasted to Word/Powerpoint/etc.

7.5 Path Diagrams

Used for: SEM/CFA/path analysis

If you are just trying to visualize the results of a SEM model fitted using the lavaan package, I recommend the semPlot package (http://sachaepskamp.com/semPlot/examples) in R. You can see examples of my implementation here: https://isaactpetersen.github.io/Principles-Psychological-Assessment/sem.html#semModelPathDiagram-sem

If you are trying to create a figure for a paper or poster, you might want something that you can draw and customize yourself. I use Adobe Illustrator for hand-drawn figures.

You can look at various options below:

• semPlot package
• Adobe Illustrator
• https://www.diagrams.net
• Onyx: https://onyx-sem.com
• yworks: https://www.yworks.com
• Microsoft Visio: https://www.microsoft.com/en-us/microsoft-365/visio/flowchart-software
• Microsoft Powerpoint
• AMOS
• Warppls
• Graphviz: https://graphviz.org
  • has an R port—this is what we use for our study flowchart via the DiagrammeR package: https://rich-iannone.github.io/DiagrammeR/index.html
