R Biplot Psych
R/biplot.psych.R In psych: Procedures for Psychological, Psychometric, and Personality Research Defines functions plotone. #rewritten Sept 18,2013 to. Rotations and transformations are either part of psych (Promax and cluster), of base R (varimax), or of GPArotation (simplimax, quartimax, oblimin, etc.). Of the various rotation/transformation options, varimax, Varimax, quartimax, bentlerT, geominT, and bifactor do orthogonal rotations.
Working on a recent project to characterize the underlying factors of urban typology, we needed a quick means of visualizing the factor loadings of each indicator. We had used the “pysch” library’s “fa” function to get the analysis done. However, a quick visualization approach was not forthcoming. One of my research assistants found this fantastic example using ‘ggplot2’. However, getting the ggplot function call to work was not quite as straightforward as in the example shown.

In case you are in a similar situation, where you have obtained the loading matrix directly from the ‘fa’ function and want to use the beautiful rendering of the ggplot facet-bar approach, below is code that you might find useful.
The additional steps involve converting the loading matrix to a dataframe and then converting the row names to a dataframe column. Ignore the descriptive factor names chosen for this example, and the input file can be dataframe or matrix.
