seriation (version 1.2-0)

register_DendSer: Register Seriation Methods from Package DendSer

Description

Register the DendSer dendrogram seriation method and the ARc criterion (Earle and Hurley, 2015).

Usage

register_DendSer()

Details

Registers the method "DendSer" for seriate. DendSer is a fast heuristic for reordering dendrograms developed by Earle and Hurley (2015) able to use different criteria. control for seriate with method "DendSer" accepts the following parameters: [object Object],[object Object],[object Object],[object Object]

For convenience the following methods (for differnt cost functions) are also provided: "DendSer_ARc" (anti-robinson form), "DendSer_BAR" (banded anti-Robinson form), "DendSer_LS" (leaf seriation), "DendSer_PL" (path length).

Note: Package DendSer needs to be installed.

Examples

register_DendSer()
list_seriation_methods("dist")

d <- dist(random.robinson(20, pre=TRUE))

## use Banded AR form with default clustering (complete-link)
o <- seriate(d, "DendSer_BAR")
pimage(d, o)

## use different hclust method (Ward) and AR as the cost function for
## dendrogram reordering
o <- seriate(d, "DendSer", control = list(method = "ward.D2", cost = "AR"))
pimage(d, o)
