faConfInt: Extract confidence bounds from psych's factor analysis object

Description

This function contains some code from a function in psych that's not exported print.psych.fa.ci but useful nonetheless. It basically takes the outcomes of a factor analysis and extracted the confidence intervals.

Usage

faConfInt(fa)

Arguments

fa

The object produced by the fa function from the psych package. It is important that the n.iter argument of fa was set to a realistic number, because otherwise, no confidence intervals will be available.

Value

A list of dataframes, one for each extracted factor, with in each dataframe three variables: A list of dataframes, one for each extracted factor, with in each dataframe three variables:

Details

THis function extract confidence interval bounds and combines them with factor loadings using the code from the print.psych.fa.ci in psych.

Examples

## Not run: 
# ### Not run because it takes too long to run to test it,
# ### and may produce warnings, both because of the bootstrapping
# ### required to generate the confidence intervals in fa
# faConfInt(fa(Thurstone.33, 2, n.iter=100, n.obs=100));
# ## End(Not run)
