Description

@talgalili

Code example:
(source: andrie/ggdendro#27)

# URL containing the dput output
url <- "https://github.com/andrie/ggdendro/files/10493161/path_clust_dput.txt"
# Read the content from the URL
dput_content <- readLines(url, warn = FALSE)
# Convert the dput output into an R object
temp <- eval(parse(text = paste(dput_content, collapse = "\n")))
# View the structure of the resulting object
str(path_clust)


plot(temp)


library(dendextend)
library(ggplot2)

# Create a complex dend:
dend <- 
   # temp_data %>%
   # dist() %>%
   # hclust() %>%
   temp %>%
   as.dendrogram() 


start.time <- Sys.time()

# # plot the dend in usual "base" plotting engine:
# plot(dend)
# Now let's do it in ggplot2 :)
ggd1 <- as.ggdend(dend)
ggplot(ggd1) # reproducing the above plot in ggplot2 :)


end.time <- Sys.time()
time.taken <- round(end.time - start.time,2)
time.taken # 

output:
Error: C stack usage 7976184 is too close to the limit
