Following "Introduction to dendextend" from Tal Galili, I applied this
code on iris data:
##
library(dendextend)
library(dendextendRcpp)
library(ggplot2)
dend2 <- iris[1:30,-5] %>% dist %>% hclust %>% as.dendrogram %>%
set("branches_k_color", k=3) %>% set("branches_lwd",
rep(1,4)) %>%
set("branches_lty", rep(1,6)) %>% set("labels_colors")
%>%
set("labels_cex", c(1.0,1.0)) %>% set("nodes_pch", 19)
%>%
set("nodes_col", c("orange", "black",
"plum", NA))
ggd2 <- as.ggdend(dend2)
ggplot(ggd2, horiz = TRUE, theme = NULL)
My problem is that the labels overlap the dendogram leafs and I have no
idea on how parameter hjust or vjust may be used to create space between
label and leaf.
Thanks for any help,
Sergio
