Title: semPlot: Unified Visualizations of Structural Equation Models

Author: Sacha Epskamp

Abstract: Structural Equation Modeling (SEM) has a long history of
representing models graphically as path diagrams, yet no dedicated software
for drawing these path diagrams currently exists. I present the freely
available semPlot package for R (Epskamp, 2013), which fills the gap between
advanced, but time-consuming, graphical software and the limited graphics
produced automatically by SEM software. In addition, semPlot offers more
functionality than drawing path diagrams: it can act as a common ground for
importing SEM results into R. Any result useable as input to semPlot can be
also represented in any of the three popular SEM frameworks, as well as
translated to input syntax for the the R packges sem and lavaan. Special
considerations are made in the package for the automatic placement of
variables, using three novel algorithms that extend earlier work of Boker, J.
McArdle, and Neale (2002)
