ladderize: Ladderize a Tree

Description

This function reorganizes the internal structure of the tree to get the ladderized effect when plotted.

Usage

ladderize(x, right = TRUE, ...)

# S3 method for dendrogram ladderize(x, right = TRUE, ...)

# S3 method for phylo ladderize(x, right = TRUE, phy, ...)

# S3 method for dendlist ladderize(x, right = TRUE, which, ...)

Arguments

x

a tree object (either a dendrogram, dendlist, or phylo)

right

a logical (TRUE) specifying whether the smallest clade is on the right-hand side (when the tree is plotted upwards), or the opposite (if FALSE).

...

Currently ignored.

phy

a placeholder in case the user uses "phy ="

which

an integer (can have any number of elements). It indicates the elements in the dendlist to ladderize. If missing, it will ladderize all the dendrograms in the dendlist.

Value

A rotated tree object

   set("labels_colors") %>% set("branches_k_color", k = 5)
set.seed(123)
dend <- shuffle(dend)

par(mfrow = c(1,3))
dend %>% plot(main = "Original")
dend %>% ladderize(TRUE) %>% plot(main = "Right (default)")
dend %>% ladderize(FALSE) %>% plot(main = "Left (rev of right)")
