WitrynaSmall loadings are conventionally not printed (replaced by spaces), to draw the eye to the pattern of the larger loadings. The print method for class "factanal" calls the "loadings" method to print the loadings, and so passes down arguments such as cutoff and sort .

Witryna16 lip 2024 · The “correlation loadings”, i.e. the correlations between each variable and the selected components (see References), are plotted as pairwise scatter plots, with concentric circles of radii given by radii. Each point corresponds to a variable. The squared distance between the point and origin equals the fraction of the variance of … WitrynaHow it is possible to do this with R? Here is the example of raw data (first several lines) over parameters. I am aware, that the solution is by somehow multiplying of this raw matrix by loadings matrix to obtain projections on PCi space, but I am a bit confused with this matrix multiplication and its order after several trials.

Witryna17 lip 2011 · 1 Answer. The answer is to use unclass to convert the loadings to a matrix. The following example illustrates this. The loadings function extracts the loadings matrix and changes the class of this matrix to loadings. When you print an object of class loadings, small values are not printed, as you observe.
