similar to: plot.dendrogram and expressions

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

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

I would like to be able to exert certain types of control over the plotting of dendrograms (representing hierarchical clusterings) that I think is best achieved by modifying the dendrogram object prior to plotting. I am using the "dendrogram" class and associated methods. Define the cluster number of each cluster formed as the corresponding row of the merge object. So, if you are

Hi All, I want to take a matrix (or data frame) and winsorize each variable. So I can, for example, correlate the winsorized variables. The code below will winsorize a single vector, but when applied to several vectors, each ends up sorted independently in ascending order so that a given observation is no longer on the same row for each vector. So I need to winsorize the variable but

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 useRs, I am working on a project involving the clustering of a large dataset. I need to extract specific sub-clusters from the parent dendrogram for further analysis. The data is too large for the use of convenient tools such as identify.clust (it selects the specific group of interest on a graph), so alternatively I have saved the plot as a large image file so that it can be printed or

Hello, Before submitting a bug report, I thought I would ask here, as recommended in http://www.r-project.org/posting-guide.html. Using R 2.8.0 under Mac OS X, I find that edge labels are misplaced when doing plot.dendrogram(..., horiz=TRUE), for example > sessionInfo() R version 2.8.0 (2008-10-20) i386-apple-darwin8.11.1 locale: en_GB.UTF-8/en_GB.UTF-8/C/C/en_GB.UTF-8/en_GB.UTF-8

I am trying to learn how to format Ascii data files for scan or read into R. Precisely for a quickie project, I found some code (at end of this email) to do exactly what I need: To cluster and graph a dendrogram from package (stats). I am stuck on how to format a text file to run the script. I looked at the dataset USArrests (which would be replaced by my data and labels) using UltraEdit. That

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.

I've rolled up R-2.8.1.tar.gz a short while ago. This is a maintenance release and fixes a number of mostly minor bugs and platform issues. See the full list of changes below. You can get it (in a short while) from http://cran.r-project.org/src/base/R-2/R-2.8.1.tar.gz or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will appear in due course.

This is the first time I have gotten to the point of wanting to submit code to (what I would consider) a major project. Specifically, I have made a small change to oggenc/audio.c. I will explain the change if necessary, but that us not the purpose of this post. Primarily, I want to know how to submit changes? Mail it to someone? Via CVS commit? If CVS, how do I get access? Also, I

Hi all, I recently learned that it is possible for `as.data.frame.matrix()` to produce a data frame with 0 columns that is also entirely missing a `names` attribute, and I think this is a bug: ``` # No `names`, weird! attributes(as.data.frame(matrix(nrow = 0, ncol = 0))) #> $class #> [1] "data.frame" #> #> $row.names #> integer(0) # This is what I expected
