Prepare an object of class sem_graph
, containing
data objects that can be rendered into a SEM graph. Using this function
allows
users to manually change the default graph specification before plotting it.
Input consists of (at least) a layout, and either nodes and edges, or
a model object.

...  Additional arguments passed to and from functions. 

edges  Object of class 'tidy_edges', or a 
layout  A matrix (or data.frame) that describes the layout; see

nodes  Optional, object of class 'tidy_nodes', created with the

rect_width  Width of rectangles (used to display observed variables), Default: 1.2 
rect_height  Height of rectangles (used to display observed variables), Default: 0.8 
ellipses_width  Width of ellipses (used to display latent variables), Default: 1 
ellipses_height  Height of ellipses (used to display latent variables), Default: 1 
variance_diameter  Diameter of variance circles, Default: .8 
spacing_x  Spacing between columns of the graph, Default: 1 
spacing_y  Spacing between rows of the graph, Default: 1 
text_size  Point size of text, Default: 4 
curvature  Curvature of curved edges. The curve is a circle segment
originating in a point that forms a triangle with the two connected points,
with angles at the two connected points equal to 
angle  Angle used to connect nodes by the top and bottom. Defaults to NULL, which means Euclidean distance is used to determine the shortest distance between node sides. A numeric value between 0180 can be provided, where 0 means that only nodes with the same xcoordinates are connected toptobottom, and 180 means that all nodes are connected toptobottom. 
fix_coord  Whether or not to fix the aspect ratio of the graph. Does not work with multigroup or multilevel models. Default: FALSE. 
model  Instead of the edges argument, it is also possible to use the
model argument and pass an object for which a method exists (e.g.,
