Create a Graphviz path diagram using lavaan syntax

Description

Converts lavaan syntax or object to graphviz code. Requires 'DiagrammeR' package.

Usage

lav_to_graph(
  m,
  layout = "dot",
  adds = NULL,
  file = NA,
  rmarkdown = FALSE,
  code.only = F,
  try.labels = T,
  label.wrap = 15,
  std = F,
  elements = c("obs", "lat.covs", "resid.covs", "resid", "slopes"),
  ...
)

Arguments

m	character, following lavaan syntax model conventions (see examples), or fitted lavaan object.
layout	Can be 'dot', 'neato', 'twopi', 'circo', or 'fdp'
adds	Any graphviz code to be added to the graph.
file	character, file name to save svg code, usually with 'svg' extension.
rmarkdown	Logical. If the function used in the context of Rmarkdown.
try.labels	Try extracting labels from the data.
label.wrap	Number of character to wrap a label
std	Whether include standardized or unstandardized estimates.
elements	Character vector. What to include in the diagram, possible values "obs", "lat.covs", "resid.covs", "resid", "slopes", and "intercepts/thresholds" (currently not supported).
...	arguments passed to DiagrammeR::grViz function.

Value

The function invisibly returns the dot code which can be edited to make more customized diagrams. You can use package DiagrammeR or any other graphviz engine, e.g. http://graphviz.it. It will most likely to be useful with large and complex models.

Examples

lav_to_graph("F =~ a1 + a2 + a3 + a4")
lav_to_graph("F =~ a1 + a2 + a3 + a4; a1 ~~ a2; d ~ F ", engine = "neato")
