plot.MxLISRELModel: Create and display a graphical path diagram for a LISREL...

In umx: Structural Equation Modeling and Twin Modeling in R

Create and display a graphical path diagram for a LISREL model.

Description

plot.MxLISRELModel produces SEM diagrams using [DiagrammeR::DiagrammeR() to create the image.

Usage

## S3 method for class 'MxLISRELModel'
plot(
  x = NA,
  std = FALSE,
  fixed = TRUE,
  means = TRUE,
  digits = 2,
  file = "name",
  labels = c("none", "labels", "both"),
  resid = c("circle", "line", "none"),
  strip_zero = TRUE,
  splines = c("TRUE", "FALSE", "compound", "ortho", "polyline"),
  min = NULL,
  same = NULL,
  max = NULL,
  ...
)

Arguments

x	A LISREL OpenMx::mxModel() from which to make a path diagram
std	Whether to standardize the model (default = FALSE).
fixed	Whether to show fixed paths (defaults to TRUE)
means	Whether to show means or not (default = TRUE)
digits	The number of decimal places to add to the path coefficients
file	The name of the dot file to write: NA = none; "name" = use the name of the model
labels	Whether to show labels on the paths. both will show both the parameter and the label. ("both", "none" or "labels")
resid	How to show residuals and variances default is "circle". Options are "line" & "none"
strip_zero	Whether to strip the leading "0" and decimal point from parameter estimates (default = TRUE)
splines	Whether to allow lines to curve: defaults to "TRUE" (nb: some models look better with "FALSE")
min	optional list of objects to group at the top of the plot. Default (NULL) chooses automatically.
same	optional list of objects to group at the same rank in the plot. Default (NULL) chooses automatically.
max	optional list of objects to group at the bottom of the plot. Default (NULL) chooses automatically.
...	Optional parameters

Details

Note: By default, plots open in your browser (or plot pane if using RStudio).

Opening in an external editor/app

The underlying format is graphviz. If you use umx_set_plot_format("graphviz"), figures will open in a graphviz helper app (if installed). If you use graphviz, we try and use that app, but YOU HAVE TO INSTALL IT!

On MacOS, you may need to associate the ‘.gv’ extension with your graphviz app. Find the .gv file made by plot, get info (cmd-I), then choose “open with”, select graphviz.app (or OmniGraffle professional), then set “change all”.

The commercial application “OmniGraffle” is great for editing these images.

m1 = umxLISREL("one_factor", data = demoOneFactor, type = "cov",
               umxPath("G", to = manifests),
               umxPath(var = manifests),
               umxPath(var = "G", fixedAt = 1))
plot(m1)
