Hi there, I've tried to install the A2R package using the files from http://addictedtor.free.fr/packages/A2R/lastVersion/ This is the error I get when trying to load the library: library(A2R) Error in library(A2R) : 'A2R' is not a valid package -- installed < 2.0.0? Can anyone please help? Thanks. Kate [[alternative HTM...

I want to change leaf color by group in hclust plot. I've seen several answers about A2R package but I cannot install A2R and Rtools in windows. Do you know how to install A2R package in windows or how to change leaf color by group in hclust plot? Thank you in advance, Soyeon

Dear List I'm trying to install a package not present in cran named A2R ( http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=79) After running the demo script I retrieve the following error: cannot change value of locked binding for '._a2r_counter' Please could someone give to me a tip about my error? Thank you very much Here is my sessionInfo()...

Hi Everyone, I'm trying to use cutree to get the clusters after hclust. What I used is: mycluster<-cutree(cnclust,h=0.5) Now, my problem is, how can I get the actual clusters? Thanks! Best, Baoqiang Cao

Dear r-list, I am trying to visually seperate the two main clusters of a dendrogram. The idea is to use: 'edgePar=list(lty=3)' for 'dend1[[1]]' and 'edgePar=list(lty=1)' for 'dend1[[2]]' I have not found a way to solve this. Any suggestions? Patrick hc <- hclust(dist(USArrests), "ave") (dend1 <- as.dendrogram(hc)) par(mfrow=c(2,2)) plot(dend1)

Hi, I have a grouping of some observations. I want to cluster them using hierarchical clustering and compare how the hierarchical clustering shows up vis-a-vis the groupings. Is it possible to do this in color? I guess what I am looking for is a way to color the labels of a hierarchical clustering plot using different colors according to the original grouping. Any suggestions? Many thanks and

Hi all, I am creating dendrograms using agnes and was wondering if it is possible to add color to the leaves (and just the leaves). For example, in the documentation, they have an example using the "votes.repub" data set. If I wanted to make the word "Washington" green (and only Washington), is it possible and if so how? I can apply "summary" to the object

Dear All, I have a cluster object based on a dissimilarity matrix from about 1,100 cases and wish to know whether anyone can think of any tips to display some form of graphical output which would give some sense of the similarity between the cases. A standard form of dendrogram would be fine, but with so many cases the dendrogram on the standard devices (R-2.20 on NT4) is very compact

Hi All R-helpers This is my first (but probartly not last ;-) mail to R-help, so hello to everybody. My problem: Is there a way to give colors to the labels (sample labels) in plots for a hclust object for better visualization? I have looked through plot, points, hclust and more but cannot find anything on label color. Anybody know if this is doable? Best regards Jeppe

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
