print.stdmod_lavaan: Print a 'stdmod_lavaan' Class Object

Description

Print the output of stdmod_lavaan().

Usage

# S3 method for stdmod_lavaan
print(x, conf = 0.95, nd = 3, ...)

Value

x is returned invisibly.

Arguments

x

The output of stdmod_lavaan().

conf

If nonparametric bootstrapping has been conducted by stdmod_lavaan(), this is the level of confidence in proportion (.95 denotes 95%), of the confidence interval. Default is .95.

nd

The number of digits to be printed.

...

Optional arguments. Ignored.
