public static ColumnSelector IsCategorical()Return Value
ColumnSelectorA selector that matches columns backed by categorical vectors.

The selector resolves against DataFrameSchema<R, C> and inspects schema metadata only. It uses IsCategorical and does not inspect level indexes, vector values, measurement scale, or future semantic categorical annotations. If no columns are categorical, it resolves to an empty selection.
