upgrade: relations

David Meyer 
Dear useRs,


a new version of the 'relations' package has appeared on CRAN. New 
features include:

   o support for fuzzy relations added

   o support for sets moved to separate 'sets' package

   o new SD fitters for the S ("symmetric") and M ("matches") families

   o fitters for Cook-Seiford method and Euclidean consensus added

   o fitters can now use a sparse constraint matrix representation

   o relations are now subsettable

   o relation_choice() for choosing "winner" objects based on an ensemble
     of relations between these

   o new summary method for relations which computes all implemented
     predicates

Best,

David and Kurt.
