similar to: change labels in a dendrogram

Hi all: I already made a dendrogram, I want to change the labels; In my data set there is one column with text that I want to set as the labels, any one can tellme how can I do it? Thanks, Ana Marcela [[alternative HTML version deleted]]

Hi I've made a dendogram but I cannot label with text that I have on one of the columns of the data, anyone can help me thanks Ana [[alternative HTML version deleted]]

Hello to all, I still have this doubt. I'd like to colour the different labels of my dendrogram each one with a different colour. How can I do? I guess I could do using *edgetext* and then *t.col* or* lab.col* but I don't know how to add edgetext to my dendrogram. Can you help me please? Example: require(graphics); require(utils) hc <- hclust(dist(USArrests), "ave") (dend1

Dear R-help list, I'd like to create visualize the clustering of a dataset with a dendrogram. I'm using the following script: data = read.table("data.csv", header=T, sep=";") require(cluster) res = as.dendrogram(agnes(data)) chlab <- function(n) { if(is.leaf(n)) { att <- attributes(n) labx <- data$category1[att$label] lab_color <- ifelse(labx ==

Hi all, Can someone tell me how to justify (right or left) the labels on the branches of a dendrogram tree? I have produced a dendrogram via agnes and plotted it with pltree. The dendrogram terminal branch labels seem to be centre-justified by default and I was hoping to change this to left justification.

Hi Sorry if this is in the help :-S I've looked at example(dendrogram) and though it gives some indication of what I want, it doesn't do all. OK, so here is what I want to do: draw a tree, and then have an action, on user-click, to either draw a sub tree or a plot of the data. I also want users to be able to search for a particular label and have it highlighted on the tree, say in

Hi, I am clustering data based on three numeric variables. I have a fourth variable that is categorical (site) which I would like to use to label the leaves of my dendrogram, so I can see how the different sites are grouped throughout the tree, but I do NOT want to use this variable in the cluster analysis itself. Is there any way I can do this? Thanks, Samantha -- View this message in

Hello, It seems that the plot function for dendrograms does not draw labels when they are too long. > hc <- hclust(dist(USArrests), "ave") > dend1 <- as.dendrogram(hc) > dend2 <- cut(dend1, h=70) > dd <- dend2$lower[[1]] > plot(dd) # first label is drawn > attr(dd[[1]], "label") <- "aaaaaaaaaaaaaaaaaa" > plot(dd) # first label is

It looks like R 3.0.0 has the same limitation as the 2.x series. When extracting labels from about 30000 node dendrogram (x=labels(h)) R throws an error: Error in match.fun(FUN) : node stack overflow Is there a way around it? Thanks, Alex

Dear R friends, I have constructed an object of class 'dendrogram' using an own function, and I'm using the R function plot.dendrogram for visualizing it. It works fine, but I could not find out how to change the font size of edge and leaf labels. ?plot.dendrogram has shown me that the coloring of the edge labels can be changed using plot(my.dendrogram,

Core developers, I couldn't find any simple way to send a vector of colors to apply to each terminal in plot.dendrogram() or plot.hclust()---I asked R-help about it a few weeks ago and didn't get any response---so I hacked that functionality into the plot.dendrgram code (see below for hacked function plus examples).... Is there any chance this functionality could be added to the

Hi, does anybody know if it is possible to use an image (rather than text) to label the leaves of a dendrogram? I realize that this will not always lead to a useful on-screen display, but ideally I'd like to directly go from the dendrogram to a PDF and on-screen viewing is not to too important for me. Also, my trees are relatively small. Any pointers would be apreciated

I'd like to be able to cut dendrograms at a height I specify and then plot the resulting subtrees. I wanted to use the dendrogram object for this purpose because there doesn't seem to be a canned way to cut a hclust object and get a list of hclust objects, but there is a function (cut) that does that for dendrograms. The problem I'm having is that when I plot a dendrogram, I

Is there any way to change the orientation of the labels on the end of the dendrograms to horizontal rather than vertical? If so, how can I do that. _____________________________________________ Patrick Richardson Biostatistician - Program of Translational Medicine Van Andel Research Institute - Webb Lab 333 Bostwick Avenue NE Grand Rapids, MI 49503 ph. 616.234.5787 This email message,

Hi, is there a way to color the branches or text label of the branches of dendrograms e.g. from hclust() according to a grouping variable. Here I have something in mind like: http://www.sigmaaldrich.com/content/dam/sigma-aldrich/life-science/biowire/biowire-fall-2010/proteome-figure-1.Par.0001.Image.gif (ectodermal, endodermal, mesodermal). /johannes

Hi! I just discovered that cutree() and cut.dendrogram() do not assign the same cluster numberings when called on the same tree. More specifically, cutree() assigns cluster numbers by order of appearance in the data, while cut.dendrogram() sorts clusters by height (see example below). I guess this is for historical reasons? I'm hit by this difference when I want to get a vector of cluster

Dear all, I have been trying the following without avail and would be very grateful for any help. From a dendrogram (recursive list of lists with some structure), I would like to obtain some information of the component lists and of the enclosing list at the same time. In dendrogram-speech I basically would like the label of the leaf and the height of the enclosing branch. A dendrogram example

Is it possible to resize the labels in a dendrogram without applying circles and triangles to edges? I tried cex.labels: plot(scoreDendogramObj, horiz=TRUE, axes=FALSE, cex.labels=0.8) but that didn't have any effect. Thanks, Alex

Hi all, I'm having a problem where by I'm trying to use the NeatMap draw.dendrogram function as it is more versatile in placement/direction of dendrograms, instead of the limited plot function. Using plot I can get my dendrograms to display the species name for each leaf of the tree. But I cannot figure out how to make this happen using draw.dendrogram.. genetic<-
