R help - Jun 2000 - Local Moran's I / Getis and Ord and Rousseauw Cluster Algorithms

Sorry for the repetition, unless I've got bad deja vu this questions been
asked before but I couldn't turn up an answer on CRAN.   Is there already
any code in existence for local dependence measures such as Moran's I or
Getis and Ord G?

Also, S-Plus has a number of interstingly named Cluster Algorithms based on
some previous stand-alone fortran algorithms (agnes, daisy etc.) which have
some interesting features (such as fuzzy clustering, and some potentially
useful validation techniques).   Are there any major obstacles to getting
these to run under R?

?? (I don't think this was here recently...).

They are in the __cluster__ (contributed) package
and have been on CRAN for a longer time now

Not that I know of. S-PLUS has these in a commercial add-on (S+SpatialStats)
and so there has been little incentive for people to write and
publicize their own.

See package cluster on CRAN.
