plot_interaction
generates an interaction plot for the effect of an antecedent
on an outcome given a mediator variable.
plot_interaction(moderated_model, intxn, dv, legend)
moderated_model |
SEMinR model that contains an interaction. |
intxn |
Name (character) of the interaction term in the structural model. Must look like a product of independent variabel and moderator (e.g., "ABC*XYZ") |
dv |
Name (character) of the dependant consutruct affected by the moderator. |
legend |
Location (character) of the legend on the plot; must be a combination of bottom|top and left|right (e.g., "bottomright"). |
