Factor Loadings in PCA

Hi,
is there any way to get factor loadings (or component coefficients) from the PCA Nodes?
Thanks,
Alfredo

Factor loadings aren’t provided directly from the PCA nodes - instead, in the PCA Compute node, you are provided with the covariance matrix of the input columns in the first port, and in the second port the spectral decomposition (consisting of eigenvalues and associated variable coefficients) of the PCA.

Hi @ScottF,
thanks! I resolved using the PCA function of the FactoMineR package in a R snippet Node…
Best,
Alfredo
