Hello, I was using the functino kgs of maptree and I've realized maptree has been removed from CRAN repository. Anybody knows why has it been removed? or where can I find the function kgs that computes the Kelley-Gardner-Sutcliffe penalty function for a hierarchical cluster tree Thank you.

...he plotting scale is wrong such that the circles overlap. I've plotted horizontal and vertical lines at x=45,50,55, and y=45,50,55, as well as two squares with side=10. The squares are also overlapping in the vertical scale. Steps to reproduce: Here are the commands I used to generate this: maptrees = function(n=1,a=1,b=1,h=2,view="horz",fg=1,np=FALSE,add=TRUE) { #n = tree density (#/m2) #a = crown horizontal radius (m) #b = crown vertical radius (m) #h = tree height (m) #view = "horz", "vert" #np = TRUE if new plot desired if (...

Hi All: I am clustering 500 genes using hclust of R. Visualizing cluster membership becomes difficult with so many genes in each cluster...Is there a way of printing the dendrogram in multiple pages so that I can clearly see what is in each cluster? Thanks in advance. Karthi.

Hi All: Package TSERIES is stated to depend on MVA. However, there is no MVA package to be found under the list of package sources.

I want to plot only a part of a denrogramm, which was produced by hclust. In S-Plus I used the function subtree, but I can not find this function or a similar one in R.

I have created a tree and want to save some of the data so that I can create a html table from it. I would like to save the output from data.ltr (see example below) to a file, but haven't found a way to do that, keeping the nice format that typing data.ltr gives me (see output below). Is there a way to do this? Example: library (maptree) library (tree)

Hi, Can anyone tell me if they know of any functions written for regression trees with a longitudinal dataset. I've got tree, rpart and maptree, but these all seem to be for univariate responses.

Look at help(sink). I have figured out how to fix up draw.tree to do factor labels correctly and will be doing that in the next few days. Meanwhile I discovered that rpart() provides factor labels in a much more satisfactory way than tree() does. Because of this and because of the additional information rpart provides about the tree building, I recommend you switch to that. > I have created

When I use the function cutree(), the numbers of the clusters are not in the same order as the plotted dendrogram. Is there any way of sorting them so that they match the tree? Is it possible to plot a dendrogram horizontally, preferably with the branches to the right? This would enable some practical composite plots, e.g. labels that were an entire table with several columns of information, or

Any idea why clusters five and six fall off the scale in the following? library(cluster) library(maptree) data(flower) dfl2<-daisy(flower,type=list(asymm=c(1,3),ordratio=7)) hdfl2<-hclust(dfl2) prune.dfl2<-prune.clust(hdfl2,k=6) plot(prune.dfl2) Of course the following will display all six clusters, but without a scale: draw.tree(prune.dfl2) Best wishes, Mikkel Mikkel Grum

Hi, I have run rpart to construct a regression tree. Is there any simple method to draw a nice picture of it, as it is usually done in books and paper to visualize the tree?

Hi, I have explored many of the R packages that construct Bayesian trees including the tgp, bart, BMA and maptree packages. I have also searched through some other packages but they do not seem to be suitable for the type of analysis I need to do. I need to construct Bayesian CART that have terminal nodes which have bivariate regressions (not multiple regressions like most of the packages do).

Dear all, I'd like to draw a color key beside a graph drawn with xyplot (lattice library). I am aware of the draw.colorkey function (grid library) but don't know how to handle it. Any hint would be appreciated. Renaud -- Dr Renaud Lancelot, v?t?rinaire CIRAD, D?partement Elevage et M?decine V?t?rinaire (CIRAD-Emvt) Programme Productions Animales

SAS has something called the "cubic criterion" cutoff for finding the most appropriate number of clusters. Does R have anything that would replicate that? I've been searching the lists and can't seem to find anything that would point me in the right direction. Thank in advance, Philip Bermingham

I am trying to create a classification tree using either tree or rpart functions but when it comes to plotting the results the formatting I get is different than what I see in all the tutorials (like http://www.youtube.com/watch?v=9XNhqO1bu0A or http://www.youtube.com/watch?v=m3mLNpeke0I&feature=related or http://www.statmethods.net/advstats/cart.html "tree for kyphosis"). I am

I'd like to change the way plot.hclust displays an hclust object. Here's a description of how it's done now, from the R documentation of hclust: In hierarchical cluster displays, a decision is needed at each merge to specify which subtree should go on the left and which on the right. Since, for n observations there are n-1 merges, there are 2^{(n-1)} possible

I'm clustering rather large data sets and would like to cut the dendrograms to get a better view of specific components. I calculate the dissimilarity matrix using daisy() because I have a mixture of variable types: factors, ordered factors and numerical variables. If I want one dendrogram, I use agnes() for the agglomerative nesting and pltree() to draw the dendrogram. That way, I get the

I have a collection of SAS code that helps people review large amounts of data on a regular basis. It does this by using SAS's proc gplot with a "by" statement to prepare as many as 400 (yes, 400) separate graphs. The code is run on a remote unix host, and displayed on the reviewer's local desktop using X11 and SAS's display manager. The process is initiated from a web

Hello, is there a package in R that would allow map drawing: coastlines, country/state boundaries, maybe topography, rivers etc? Thanks for any guidance, Mark

Hello everyone I hope Im not bothering you all again. I have just begun to use R and so Im not yet familiarized with it.. I ve got an assignment which consists in calculating the area of a circle given a certain radius and center using the monte carlo method, which means that I have to plot a circle given its parameters. Limit the area inside it...with as many sample points as possible...and
