similar to: text labels on 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]]

I'm trying to plot a dendrogram object which is created using "as.dendogram" function. It works fine however I can not change the yaxis limits of the plot. tree<-as.dendrogram(hclust(as.dist(dissim),method="single")) plot(tree,ylim=range(0,20)) Error in plot.default(0, xlim = xlim, ylim = ylim, type = "n", xlab = xlab, : formal

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

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 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

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

I am using R for hierarchical clustering of a number of documents. I have a distance matrix on which I have applied hclust method. When I plot the result of hclust method, I can see the dendogram plotted. What I need now is the dendogram stored as a tree in a data structure. My goal is to automatically label all internal nodes. For that, I need to know, which leaf nodes make a first level

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.

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,

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

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

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,   I need to generate a heatmap on a square matrix and wouldn't want to reorder the columns and the rows on the heatmap display.    I have used the options Rowv=NULL and Colv=NULL but doesn't seem to work. Following is a snippet of the heatmap function i am using. args <- commandArgs(); inputfile <- args[2] imgfile   <- args[3] bitmap(imgfile, height=15, width=15, res=100,

Dear R-help, I have performed a hierarchical clustering on some data that I have and would like to know some nice ways of visualizing it. I have 2 related questions: i) How to color the labels AND the terminal branch of a dendogram? This is my inelegant way of just getting the colored labels. data(iris) # Formatting data into required format ir <- iris[ ,-5] ir.class <- c(

Hi all, Hi Gavin, thx for your help i finally found out what i want to do and how to fix it. just needed to get some more level my cut level was too small... two question remain... a) can i somehow scale the twigs after cutting ? b) how can i label the nodes and how to label which one... thx !! -m.

Dear List I am having problems to set text labels in a scatter plot. At some areas dots are close and labels overlap and texts cannot be read. I have too many dots to adjust this manually. Is there any function that will calculate the label offsets to avoid this overlapping problem?

Hi everyone, I am using the fastgreedy.community function to get the $merges matrix and the $modularity vector. This serves my purpose of testing modularity of my graph. But I am "greedy" to plot the heat map and dendrrogram based on the $merges dendogram matrix. I know that heatplot does the graphics part but I am not sure if the dendogram generated by the heatplot will match the one

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
