Arguments

lavaan_object

lavaan object of a univariate or bivariate latent change score model.

layout

Matrix, specifying number and location of manifest and latent variables of LCS model specified in lavaan_object.

lavaan_syntax

String, lavaan syntax of the lavaan object specified in lavaan_object. If lavaan_syntax is provided a layout matrix will be generated automatically.

return_layout_from_lavaan_syntax

Logical, if TRUE and lavaan_syntax is provided, the layout matrix generated for semPaths will be returned for inspection of further customisation.

lcsm

String, specifying whether lavaan_object represent a "univariate" or "bivariate" LCS model.

lcsm_colours

Logical, if TRUE the following colours will be used to highlight different parts of the model: Observed variables (White); Latent true scores (Green); Latent change scores (Blue) ; Change factors (Yellow).

curve_covar

See semPaths.

what

See semPlot. "path" to show unweighted grey edges, "par" to show parameter estimates as weighted (green/red) edges

whatLabels

See semPaths. "label" to show edge names as label, "est" for parameter estimates, "hide" to hide edge labels.

edge.width

See semPaths.

node.width

See semPaths.

border.width

See semPaths.

fixedStyle

See semPaths.

freeStyle

See semPaths.

residuals

See semPaths.

label.scale

See semPaths.

sizeMan

See semPaths.

sizeLat

See semPaths.

intercepts

See semPaths.

fade

See semPaths.

nCharNodes
