Description: An R package was developed to implement diverse previously proposed numerical strategies to determine the number of components/factors to retain in PCA or PA. The considered strategies can be classified into three categories: heuristics, likelihood ratio tests and simulations. The package also implements complementary graphical and utilitarian functions: Accordingly, to palliate convergence problems with some factor analysis estimations functions implemented in R, two simpler and less precise estimations methods are available: iterated or not principal axis analysis. Also, functions useful to design simulation of principal components and factor structure are available.
