A dendrogram with both of the root's branches of the same height

Examples

# NOT RUN {
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")
# }
