How to plot a lavaan SEM path model?

[jeromyanglim]

qgraph seems well suited, but it seems to be under active development. My first example did not work, because I don't think indirect effects are supported.

qgraph.lavaan() function is designed for the purpose.

It required a little bit of fiddling with options to produce something legible.

qgraph.lavaan(lavaan_fit, layout='circle', include=3, vsize.man=5)

• There's an example here usign graphViz: http://web.missouri.edu/~kolenikovs/graphviz_sem.html
• There's an example here using the pathDiagram function in the sem package. Example1 and Example 2
• OpenMx supports outputting Graphvix objects with explanation here: http://openmx.psyc.virginia.edu/wiki/omxgraphviz-help-making-path-diagrams
• The diagram package in R provides another option. See this vignette
