horizontal dendrogram in R with labels

问题 I am trying to draw a dendrogram from the hclust function output. I hope the dendrogram is horizontally arranged instead of the default, which can be obtain by (for example) require(graphics) hc <- hclust(dist(USArrests), "ave") plot(hc) I tried to use as.dendrogram() function like plot(as.dendrogram(hc.poi),horiz=TRUE) but the result is without meaningful labels: If I use plot(hc.poi,labels=c(...)) which is without the as.dendrogram() , I can pass the labels= argument, but now the dendrogram

问题 This question was migrated from Cross Validated because it can be answered on Stack Overflow. Migrated 6 years ago . I would like to create a dendrogram in R which has colored branches, like the one shown below. So far I used following commands to create a standard dendrogram: d <- dist(as.matrix(data[,29])) # find distance matrix hc <- hclust(d) # apply hirarchical clustering plot(hc,labels=data[,1], main="", xlab="") # plot the dendrogram How should I modify this code to obtain desired

问题 I`m making a cluster plot from my data. I have the entire plot finished but my label text is to large to be able to properly read the plot. Anyone any idea how to make labels smaller. I am using the package "sparcl", and my function is: ColorDendrogram(fit,y=col.int, main = "Clusters from 216 samples", branchlength = 0.20, labels = fit$labels, xlab = NULL, sub = NULL, ylab = "", cex.main = NULL) as you can see the branch text is to big and they fall over each other. I want the text of the

问题 I have clustering code written in Java, from which I can create a nested tree structure, e.g. the following shows a tiny piece of the tree where the two "isRetired" objects were clustered in the first iteration, and this group was clustered with "setIsRequired" in the fifth iteration. The distances between the objects in the clusters are shown in parentheses. |+5 (dist. = 0.0438171125324851) |+1 (dist. = 2.220446049250313E-16) |-isRetired |-isRetired |-setIsRetired I would prefer to present

问题 I have a dendrogram in R. It is based on hierachical clustering using hclust. I am colouring labels that are different in different colours, but when I try changing the labels of my dedrogram (to the rows of the dataframe the cluster is based on) using dendrogram = dendrogram %>% set("labels", dataframe$column) the labels are replaced, but in the wrong positions. As example: My dendrogram looks like this: ___|___ | _|_ | | | | 1 0 2 when I now try changing the labels like specified above, the

Plotting hierarchical clustering dendrograms for large data sets

问题 I have a huge data set of time series data. In order to visualise the clustering in python, I want to plot time series graphs along with the dendrogram as shown below. I tried to do it by using subgrid2plot() function in python by creating two subplots side by side. I filled first one with series graphs and second one with dendrograms. But once number of time series increased, it became blur. Can someone suggest a nice way to plot this type of dendrogram? I have around 50,000 time series to

dendrapply Error: C stack usage is too close to the limit

问题 I'm using R 's dendrapply this way: dendrapply(dendro, function(n) utils::str(attributes(n))) where dendro is a 'dendrogram' with 2 branches and 5902 members total, at height 2 . After a while that it's running it crashes with this error: Error: C stack usage 7971524 is too close to the limit Any idea? 回答1: It looks like you have an infinite recursion situation which has arisen because the nodes are not returned in your function. If you are just looking to print the structure of the

问题 This question already has an answer here : Colour the tick lables in a dendrogram to match the cluster colours (1 answer) Closed 2 years ago . I want to change the color of lines in the dendrogram corresponding to its label. However, I haven't seen anything like that before. So I want to at least change the color of the text labels. 回答1: It seems like there is no simple solution for that. The labels of the dendrogram are simply the y-axis tick labels and are all sharing the same color
