R: Creating a dendlist object from several dendrograms

dendlist {dendextend} | R Documentation

## 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

### Examples

    ## Not run:

    dend <- iris[,-5] %>% dist %>% hclust %>% as.dendrogram
    dend2 <- iris[,-5] %>% dist %>% hclust(method = "single") %>% as.dendrogram
    dendlist(1:4, 5, a=dend) # Error
    # dendlist <- function (...) list(...)
    dendlist(dend)
    dendlist(dend, dend)
    dendlist(dend, dend, dendlist(dend))
    #  notice how the order of
    dendlist(dend, dend2)
    dendlist(dend) %>% dendlist(dend2)
    dendlist(dend) %>% dendlist(dend2) %>% dendlist(dend)
    dendlist(dend, dend2) %>% tanglegram
    tanglegram(tree1 = dendlist(dend, dend2))

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

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