untangle_DendSer: Tries to run DendSer on a dendrogram

Description

The function tries to turn the dend into hclust. It then uses the cophenetic distance matrix for optimizing the tree's rotation.

This is a good (and fast) starting point for untangle_step_rotate_2side

Usage

untangle_DendSer(dend, ...)

Value

A dendlist object with ordered dends

Arguments

dend

An object of class dendlist

...

NOT USED

Examples

if (FALSE) {
set.seed(232)
ss <- sample(1:150, 20)
dend1 <- iris[ss, -5] %>%
  dist() %>%
  hclust("com") %>%
  as.dendrogram()
dend2 <- iris[ss, -5] %>%
  dist() %>%
  hclust("sin") %>%
  as.dendrogram()
dend12 <- dendlist(dend1, dend2)

# bad solutions
dend12 %>% tanglegram()
dend12 %>%
  untangle("step2") %>%
  tanglegram()
dend12 %>%
  untangle_DendSer() %>%
  tanglegram()
# but the combination is quite awsome:
dend12 %>%
  untangle_DendSer() %>%
  untangle("step2") %>%
  tanglegram()
}
