Plotting of Piecewise Structural Equation Models
plot.psem uses [DiagrammeR] to generate path diagrams of 'piecewiseSEM“ fits within R.
## S3 method for class 'psem' plot( x, return = FALSE, node_attrs = data.frame(shape = "rectangle", color = "black", fillcolor = "white"), edge_attrs = data.frame(style = "solid", color = "black"), ns_dashed = T, alpha = 0.05, show = "std", digits = 3, add_edge_label_spaces = TRUE, ... )
x |
a [psem()] object |
return |
whether to return the output from [DiagrammeR::create_graph()] for modification and later plotting |
node_attrs |
List of node attributes to override defaults of rectangular nodes with black outline and white fill. See [here](http://visualizers.co/diagrammer/articles/node-edge-data-frames.html) and [here](http://visualizers.co/diagrammer/articles/graphviz-mermaid.html) for a more complete rundown of options. |
edge_attrs |
List of edge attributes to override defaults of solid black arrows. See [here](http://visualizers.co/diagrammer/articles/node-edge-data-frames.html) and [here](http://visualizers.co/diagrammer/articles/graphviz-mermaid.html) for a more complete rundown of options. |
ns_dashed |
If TRUE, paths that are not different from 0 will be dashed rather than solid, unless the whole is overridden in 'edge_attrs' |
alpha |
The alpha level for assessing whether a path is different from 0 |
show |
What types of path coefficients are shown? Default '"std"' is standardized coefficients. For undstandardized, use '"unstd"' |
digits |
How many significant digits should be shown? |
add_edge_label_spaces |
Should spaces by added on either side of edge labels? Default is 'TRUE' as otherwise paths too often overlap edges. |
... |
Other arguments to [DiagrammeR::render_graph()] |
Returns an object of class [DiagrammeR::dgr_graph]
