Convert Objects to Class hclust

Description:

     Converts objects from other hierarchical clustering functions to
     class `"hclust"'.

Usage:

     as.hclust(x, ...)
     as.hclust.twins(x, ...)

Arguments:

       x: Hierarchical clustering object

     ...: further arguments passed to or from other methods.

Details:

     Currently there is only support for converting objects of class
     `"twins"' as produced by the functions `diana' and `agnes' from
     the package `cluster'.

Value:

     An object of class `"hclust"'.

See Also:

     `hclust', `diana', `agnes'

Examples:

     x <- matrix(rnorm(30), ncol=3)
     hc <- hclust(dist(x), method="complete")

     library(cluster)
     ag <- agnes(x, method="complete")

     x11()
     par(mfrow=c(1,2))
     plot(hc)
     mtext("hclust", side=1)
     plot(as.hclust(ag))
     mtext("agnes", side=1)
