Hi, you can try this:

https://rdrr.io/rforge/Gifi/man/princals.html

"princals: Categorical principal component analysis (PRINCALS).

Fits a categorical PCA. The default is to take each input variable as ordinal but it works for mixed scale levels (incl. nominal) as well. Through a proper spline specification various continuous transformation functions can be specified: linear, polynomials, and (monotone) splines."
