fa_plot_loadings: Plot factor loadings

In Deleetdk/kirkegaard: kirkegaard

Plot factor loadings

Description

Returns a ggplot2 plot with sorted loadings colored by the analysis they belong to. Supports reversing of any factors that are reversed. Dodges to avoid overplotting.

Usage

fa_plot_loadings(
  fa_objects,
  fa_labels = NA,
  factor_names = NA,
  reverse_vector = NA,
  reorder = "mean",
  clean_factor_labels = T,
  clean_indicator_labels = T
)

Arguments

fa_objects	(list of fa-class objects) Factor analyses objects from the fa() function from the psych package.
fa_labels	(chr vector) Names of the analyses.
factor_names	(chr vectr) Names of the factors if multiple.
reverse_vector	(num vector) Vector of numbers to use for reversing factors. Use e.g. c(1, -1) to reverse the second factor. Defaults not reversing.
reorder	(chr scalar or NA) Which factor analysis to order the loadings by. Can be integers that reprensent each factor analysis. Can also be "mean", "median" to use the means and medians of the loadings. Use "all" for the old method. Default = "mean".

Details

Non-overlapping indicates are put in the bottom. Note that internally, x and y coods have been flipped, so to modify the scales, use the opposite command, e.g. ylim to modify x axis limits.

Examples

library(psych)
fa_plot_loadings(fa(iris[-5])) #extract 1 factor and plot
fa_plot_loadings(fa(iris[-5], 2)) #extract 2 factors and plot
#list of FAs
fa_list = list(part1 = fa(iris[1:50, -c(1, 5)]),
                part2 = fa(iris[51:100, -c(2, 5)]),
                part3 = fa(iris[101:150, -c(3, 5)]))
#notice that it handles non-overlapping indicators
fa_plot_loadings(fa_list)
#reorder by a particular FA
fa_plot_loadings(fa_list, reorder = 1)
