## S3 Generics:
export(clusplot, pltree, silhouette, volume)
## Normal functions (non-generics, non-methods):
## The original constructors:
export(agnes, clara, daisy, diana, fanny, mona, pam)
## and the rest
export(bannerplot, ellipsoidhull, ellipsoidPoints,
       clusGap, maxSE,

## Methods also useful as 'standalone functions':
export(predict.ellipsoid)
export(coef.hclust, coefHier)

## For now, we keep *depending* on 'stats' just so that
## S3 methods *.hclust, *.dist etc will work

           identify, mtext,
           par, plot, points, polygon, rect, segments, text, title)
