If you Web search for "splus help" or similar, you will find, among
others,

  http://www.uni-muenster.de/ZIV/Mitarbeiter/BennoSueselbeck/s-html/shelp.html

and there under "is.category"

  "Creates or tests for categorical objects (vectors with a
"levels" attribute).
   This function is deprecated; factor or ordered are now preferred."
