[R-pkgs] New package: sets

[David Meyer]

Dear useRs,

The new 'sets' package made it to CRAN, supporting:

o data structures for sets, fuzzy sets, multisets, and fuzzy multisets
o the use of (most) R objects as elements
o standard set operations (union, intersection, complement, Cartesian 
product, power set, ...)
o support for several fuzzy logic systems

An introductory vignette is also available.

David and Kurt.
