Problem extracting eigen value data from PCA report when using 'by'
Hello, I running a PCA on a data table independently for several categories (specimen_material_type).For each category, I want to save the eigenvalues of principal components into an eigenvalue data table labelled 'Eigenvalue for XYZ'. In the example table, I have 2 categories. I manage to retrieve the first set of values using a For loop but then it crashes for the second category. Any suggestion...
