Show More Major Options in an Output of 'lavaan'

Description

Display the values of more major options in a model fitted by lavaan::lavaan() or its wrappers (e.g., lavaan::sem or lavaan::cfa()).

Usage

show_more_options(fit)

## S3 method for class 'show_more_options'
print(x, ...)

Arguments

fit

An output of lavaan::lavaan() or its wrappers (e.g., lavaan::cfa() and lavaan::sem())

x

The output of show_more_options().

...

Additional arguments. Ignored.

Details

It extracts the values of major options in the output of lavaan::lavaan() or its wrappers (e.g., lavaan::sem or lavaan::cfa(). Most of the values are also reported in the summary of a lavaan object. This function is used to show the values in one single table for a quick overview.

It checks the actual values, not the call used. This is useful for understanding how a prepackaged estimator such as ML, MLM, and MLR set other options. It supports the following options:

• Estimator (estimator)

• Standard error (se)

• Model chi-square test(s) (test)

• Missing data method (missing)

• Information matrix used for computing standard errors (information)

• Information matrix used for computing model chi-square (information)

• Whether the mean structure is included.

It is named show_more_options() to differentiate it from show_options(), originally in the semunpack package, which is intended for new users of lavaan. The code is adapted from show_options with more advanced options added.

Value

A show_more_options-class object with a print method that formats the output.

Methods (by generic)

• print(show_more_options): The print method of the output of show_more_options().
