2002-01-22  Martin Maechler  <maechler@stat.math.ethz.ch>

	* R/ellipsehull.R (ellipsehull) et al:
	  generalized from 2 to p dimensions. -- points generation: not yet!

	* tests/ellipsehull.R: new test file

	* man/clusplot.partition.Rd: clean up
	* man/clusplot.default.Rd: proper reference to Pison et al
	* man/clusplot.Rd: clean

2002-01-21  Martin Maechler  <maechler@stat.math.ethz.ch>

	* R/ellipsehull.R (ellipsehull) and others: new functions
	* R/plotpart.q (clusplot.default) use new ellipsePoints();
	  simplification by using "d2" (= dist^2) instead of "dist".

2002-01-19  Martin Maechler  <maechler@stat.math.ethz.ch>

	* R/plotpart.q (clusplot.default) re-scale cov.wt() result:
	  Finally return the smallest possible ellipses.

	  NOTA BENE ===>  (numerical) results are *different* !

2002-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>

	* R/plotpart.q (clusplot.default) {spannel}: Finally found why our
	ellipses are not quite ok : R's cov.wt() differs from S-plus' !

	* src/spannel.f (spannel): new argument `maxit' (was 5000).

	* R/plotpart.q (cusplot.default): cleanup, eliminating internal
	  kleur() & plotje(); and "spannel" arguments; new maxit; lower eps
	  use which.min() and which.max(); ...

	* R/pam.q (pam): diss has new default  = inherits(x, "dist") which
	  is TRUE therefore for dissimilarity or dist objects.

2002-01-18  Martin Maechler  <maechler@stat.math.ethz.ch>

	calling functions.

	* man/cluster-internal.Rd: new for formerly local functions, now in
	* R/internal.R (sizeDiss),
	* R/internal.R (lower.to.upper.tri.inds), and upper.to...:
	new functions instead of local functions in several places, e.g.,
	* R/diana.q, R/fanny.q, ...

	* R/plotpart.q (clusplot.default):
	fix bug PR#1249: cmd() != cmdscale(); use new cmdscale(*, add=TRUE)
	 ---> (slightly) different result sometimes
	fix long-standing typo in NA case + more cleanup

	* R/plotpart.q (clusplot.partition):
		explicit `main' argument with better default.
