    leaf_labels = TRUE, rotate = FALSE,
    theme_dendro = TRUE, ...)

data

Either a dendro object or an object that can be coerced to class dendro using the dendro_data function, i.e. objects of class dendrogram, hclust or tree

segments

If TRUE, show line segments

labels

if TRUE, shows segment labels

leaf_labels

if TRUE, shows leaf labels

Examples

library(ggplot2)
hc <- hclust(dist(USArrests), "ave")
### demonstrate plotting directly from object class hclust
p <- ggdendrogram(hc, rotate=FALSE)
print(p)
ggdendrogram(hc, rotate=TRUE)
### demonstrate converting hclust to dendro using dendro_data first
hcdata <- dendro_data(hc)
ggdendrogram(hcdata, rotate=TRUE, size=2) + labs(title="Dendrogram in ggplot2")
