title: Flip ggdendrogram plot
body: <p>I'm using a ggdendrogram to plot a dendrogram, but I want to have the labels on the left to make the graph more intuitive. How do I do this? Thanks!!!</p>
  
  <pre><code>library(ggplot2)
  library(ggdendro)
  
  ### Data
  countries &lt;- c("UK","AU","SA","CH")
  distmatrix &lt;- matrix(c(0.00, 0.16, 1.01, 0.97, 0.16, 0.00, 0.84, 0.79, 1.01, 0.84, 0.00, 1.49, 0.97, 0.79, 1.49, 0.00),
  nrow=4,dimnames=list(countries, countries))
  
  ### Cluster
  hc = hclust(as.dist(distmatrix), method = "ward")
  
  ### Plot
  ggdendrogram(hc, rotate=TRUE, theme_dendro=FALSE)
  </code></pre>
