The function makes sure the two branches of the root of a dendrogram will have the same height.
The user can choose how to decide which height to use.
flatten.dendrogram(dend, FUN = max, new_height, ...)
Arguments
- dend
dendrogram object
- FUN
how to choose the new height of both branches (defaults to taking the max between the two)
- new_height
overrides FUN, and sets the new height of the two branches manually
- ...
passed on (not used)
Value
A dendrogram with both of the root's branches of the same height
Examples
hc <- hclust(dist(USArrests[2:9, ]), "com")
dend <- as.dendrogram(hc)
attr(dend[[1]], "height") <- 150 # make the height un-equal
par(mfrow = c(1, 2))
plot(dend, main = "original tree")
plot(flatten.dendrogram(dend), main = "Raised tree")
