Dear useRs,

Version 0.2 of package "relations" appeared on CRAN and is currently 
propagating to the mirrors. In addition to some bug fixes, the new 
release includes:

   o an introductory vignette showing the main features;

   o new SD fitters for the C ("complete") and A ("antisymmetric")
     families of relations;

   o a fitter for Copeland's method;

   o the relation_classes() function to extract and pretty-print
     (ordered) classes from preferences and equivalences;

   o the function relation_violations() to compute a measure of
     remoteness from a specified property (e.g., symmetry,
     transitivity, etc.).

David and Kurt.
