‘semPlot’ is a new package that can be used for unified visualizations of SEM models. The developmental version is available on GitHub and a stable version is available at CRAN.

Important note for Mac users:

semPlot depends via qgraph on the Tcl/Tk interface. This might need to be installed via http://cran.us.r-project.org/bin/macosx/tools/ or R might crass when semPlot is loaded!

Installation under Ubuntu:

1. Make sure to update R to the latest version, 3.0.2. Here’s how to do that.
2. Then, manually install XML. Instructions are here.
3. Now, install semPlot the regular way.

Thanks to Simon Hadlich for this guide!

Known issues:

• In the CRAN release single indicators are bugged. (fixed in next version)
• Using MplusAutomation 0.6, you need to load MplusAutomation before running semPlot with an mplus argument or you will encounter an error. (fixed in next version)

3. Standardization of intercepts is not yet supported.
