Description

There is a R package [KPC](https://cran.r-project.org/web/packages/KPC/) that implements a more general and improved version of FOCI, called KFOCI (Kernel FOCI), that was proposed by Huang et al. The improvement over existing methods in certain settings is quite remarkable, thus I believe it would be a great addition to have functions similar to the ones for FOCI. What do you think?
For categorical variables, it may even be possible to partially (i.e. as long as they have an order) refrain from creating dummy variables by using them as integer-based variables.

Research direction

Review the repository's existing FOCI functions and compare them with the KPC R package and the KFOCI method proposed by Huang et al. Clarify the desired API, supported categorical-variable behavior, and acceptance criteria before implementation; done should mean the requested KFOCI functionality is integrated with coverage for the agreed cases.
