Map FactoMineR category labels to legacy naming patterns

factominer_category_map(X, element = c("quali.var", "quali.sup", "var"))

Arguments

X: a FactoMineR object (MCA, MFA, FAMD, HMFA).
element: element to map. Use "var" for MCA categories or "quali.var" for MFA/FAMD/HMFA qualitative categories. "quali.sup" maps supplementary qualitative categories when available.

Value

A data.frame with current labels, variable names, levels, and legacy naming patterns.

Examples

# \donttest{
if (requireNamespace("FactoMineR", quietly = TRUE)) {
  data(poison)
  res.mca <- FactoMineR::MCA(poison, quanti.sup = 1:2, quali.sup = 3:4, graph = FALSE)
  head(factominer_category_map(res.mca, element = "var"))
