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.
