Exploratory factor analysis based on the psych::fa function
exploratory_fa.RdCreates a data frame with factor loadings and variance explained.
Arguments
- ...
Arguments passed to the psych::fa function.
- factor_names
A character vector with names for the resulting factors. If not provided, default names are chosen.
- sort
If TRUE, loadings are sorted.
- cut
Loadings below cut will be omitted in the resulting data frame.
- round
Number of digits to round loadings (based on the base::round function).
