Lists Implemented R6 Special Sets

Lists special sets that can be used in Set.

listSpecialSets(simplify = FALSE)

Arguments

simplify	logical. If FALSE (default) returns data.frame of set name and symbol, otherwise set names as characters.

Value

Either a list of characters (if simplify is TRUE) or a data.frame of SpecialSets and their traits.
