Layout messed up when ggplotting an hanged dendrogram

[theclue]

I noticed some layout glitches when trying to plot the iris example with the 'hanged' option in ggplot. Here the reproducible example:

dend <- iris[1:30,-5] %>% dist %>% hclust %>% as.dendrogram %>% hang.dendrogram(hang = 0.1) %>%
  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)) %>% 
  set("nodes_pch", 19) %>% set("nodes_col", c("orange", "black", "plum", NA))
# plot the dend in usual "base" plotting engine:
plot(dend, horiz=TRUE)

# Now let's do it in ggplot2 :)
ggd1 <- as.ggdend(dend)
library(ggplot2)
# the nodes are not implemented yet.
ggplot(ggd1) # reproducing the above plot in ggplot2 :)

and here's the output...it doesn't look very good :)

tnx for this wonderful package and have a nice day! gabriele

Hi gabriele, Thank you for the report and the kind words.

I get a different plot from the one you presented. I did updated the relevant functions in dendextend recently on CRAN. Could you please install the package again, and see if you get the same result?

Cheers, Tal

Uhm...I installed the package today, so I'm sure I have the latest version.

I'll try to reproduce at office, where I have a different environment, and I'll post here the plot.

I'll be back in a couple of hours :) gabriele

I get the same result as in Gabriele’s original message. Best,

Greg.

Thanks Greg, I can't seem to reproduce the problem. I checked it on two computers (both are PC, and I see yours is Mac, maybe the problem relates to that in some way). If you get any warnings or errors - please let me know. For now, I can't reproduce it.
