ggdend / ggplotly - space the labels a bit

[talgalili]

This looks a bit worse than the based graphics version:

library(dendextend)
# library(ggdendro)
# Create a complex dend:
dend <- iris[1:30,-5] %>% dist %>% hclust %>% as.dendrogram %>% 
   set("branches_k_color", k=3) %>% set("branches_lwd", c(1.5,1,1.5)) %>% 
   set("branches_lty", c(1,1,3,1,1,2)) %>%  
   set("labels_colors") %>% set("labels_cex", c(.9,1.2)) 
# plot the dend in usual "base" plotting engine:   
plot(dend)
# Now let's do it in ggplot2 :)
ggd1 <- as.ggdend(dend)
library(ggplot2)
ggplot(ggd1) # reproducing the above plot in ggplot2 :)
