Description

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

Usage

as.hclust(x, …)

Arguments

x

Hierarchical clustering object

further arguments passed to or from other methods.

Value

An object of class "hclust".

Details

Currently there is only support for converting objects of class "twins" as produced by the functions diana and agnes from the package cluster. The default method throws an error unless passed an "hclust" object.

Examples

Run this code
# NOT RUN {
x <- matrix(rnorm(30), ncol = 3)
hc <- hclust(dist(x), method = "complete")

# }
# NOT RUN {
if(require("cluster", quietly = TRUE)) {# is a recommended package
  ag <- agnes(x, method = "complete")
  hcag <- as.hclust(ag)
  ## The dendrograms order slightly differently:
  op <- par(mfrow = c(1,2))
  plot(hc) ;  mtext("hclust", side = 1)
  plot(hcag); mtext("agnes",  side = 1)
  detach("package:cluster")
}
# }
