ggdendrogram function

Creates dendrogram plot using ggplot.

This is a convenience function

ggdendrogram(
  data,
  segments = TRUE,
  labels = TRUE,
  leaf_labels = TRUE,
  rotate = FALSE,
  theme_dendro = TRUE,
  ...
)

Arguments

• 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
• rotate: if TRUE, rotates plot by 90 degrees
• theme_dendro: if TRUE, applies a blank theme to plot (see theme_dendro())
• ...: other parameters passed to ggplot2::geom_text()

Returns

A ggplot2::ggplot() object

Examples

### Demonstrate ggdendrogram

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")
