Extract the Indirect Effects from a 'indirect_list' Object

Return the estimates of the indirect effects in the output of many_indirect_effects().

Usage

# S3 method for class 'indirect_list'
coef(object, ...)

Arguments

object

The output of many_indirect_effects().

...

Optional arguments. Ignored by the function.

Value

A numeric vector of the indirect effects.

Details

It extracts the estimates in each 'indirect'-class object in the list.

If standardized effect is requested when calling many_indirect_effects(), the effects returned are also standardized.
