The sem method for the standard generic function effects computes total, direct,
and indirect effects for a fitted structural equation model according to the method described in Fox (1980).
# S3 method for sem
effects(object, ...)
# S3 method for msem
effects(object, ...)# S3 method for semeffects
print(x, digits = getOption("digits"), ...)
# S3 method for semeffectsList
print(x, digits = getOption("digits"), ...)
effect.sem returns an object of class semeffects with Total, Direct, and Indirect elements.
a fitted structural-equation model object produced by the sem function.
an object of class semeffects or semeffectsList, produced by effects.
digits to print.
