Flip leaves

Rotate a branch in a tree so that the locations of two bundles of leaves are flipped.

flip_leaves(dend, leaves1, leaves2, ...)

Arguments

dend

a dendrogram object

leaves1

a vector of leaves order value to flip.

leaves2

a (second) vector of leaves order value to flip.

...

not used

Value

A dendrogram object with flipped leaves.

Details

This function is based on a bunch of string manipulation functions. There may be a smarter/better way for doing it...

Examples

if (FALSE) { # \dontrun{
dend1 <- USArrests[1:5, ] %>%
  dist() %>%
  hclust() %>%
  as.dendrogram()
dend2 <- flip_leaves(dend1, c(3, 5), c(1, 2))
tanglegram(dend1, dend2)
entanglement(dend1, dend2, L = 2) # 0.4
