dendlist: Creating a dendlist object from several dendrograms

In dendextend: Extending 'dendrogram' Functionality in R

Creating a dendlist object from several dendrograms

Description

It accepts several dendrograms and or dendlist objects and chain them all together. This function aim to help with the usability of comparing two or more dendrograms.

Usage

dendlist(..., which)

## S3 method for class 'dendlist'
plot(x, which = c(1L, 2L), ...)

Arguments

...	several dendrogram/hclust/phylo or dendlist objects If an object is hclust or phylo - it will be converted into a dendrogram.
which	an integer vector of length 2, indicating which of the trees in the dendlist object should be plotted (relevant for dendlist) When used inside dendlist, which is still an integer, but it can be of any length, and it can be used to create a smaller dendlist.
x	a dendlist object

Details

It there are list() in the ..., they are omitted. If ... is missing, it returns an empty dendlist.

Value

A list of class dendlist where each item is a dendrogram

# dendlist <- function (...) list(...)

#  notice how the order of
dendlist(dend, dend2)
dendlist(dend) %>% dendlist(dend2)

  dendlist(dend2) %>%
  dendlist(dend)
dendlist(dend, dend2) %>% tanglegram()

  hclust() %>%
  as.dendrogram()
dend2 <- iris[1:20, -5] %>%
  dist() %>%
  hclust(method = "single") %>%
  as.dendrogram()

x <- dendlist(dend, dend2)
plot(x)
