## Get height attributes from a dendrogram

### Description

Get height attributes of a dendrogram's branches

### Usage

    get_branches_heights(dend, sort = TRUE, decreasing = FALSE,
      include_leaves = FALSE, ...)

### Arguments

`dend` | a dendrogram.
`sort` | logical. Should the heights be sorted?
`decreasing` | logical. Should the sort be increasing or decreasing? Not available for partial sorting.
`include_leaves` | logical (FALSE). Should the output include the leaves value (0's).
`...` | not used.

### Value

a vector of the dendrogram's nodes heights (excluding leaves).

### Examples

    hc <- hclust(dist(USArrests[1:4,]), "ave")
    dend <- as.dendrogram(hc)
    get_branches_heights(dend)

    ## Not run:
    dat1 <- iris[1:150,-5]
    dat1 <- rbind(dat1,dat1,dat1,dat1,dat1,dat1,dat1)
    dend = as.dendrogram(hclust(dist(dat1)))
    library(microbenchmark)
    library(dendextendRcpp)
    microbenchmark(
       dendextendRcpp::dendextendRcpp_get_branches_heights(dend),
       old_get_branches_heights(dend,sort=F)
