Hi, I have produced a dendrogram of categorical data in R using the hclust function, although the input was a dissimilarity matrix produced in SAS, as I have defined my own distances. The dendrogram is fine and I can view and use this. However, I was wondering if there is a method by which I can find out the optimal place to place groups, rather than relying on my visual analysis? I don't

Dear R-Help, I have a clustering problem with hclust that I hope someone can help me with. Consider the classic hclust example: hc <- hclust(dist(USArrests), "ave") plot(hc) I would like to cut the tree up in such a way so as to avoid small clusters, so that we get a minimum number of items in each cluster, and therefore avoid singletons. e.g. in this example, you can see

I want to analyze the co-occurrence of some species. In some papers, the authors said that the index"the number of species combinations (COMBO)" is a good index. I try to calculate the index by R language. But I can not get the right value. I think that I do not understand the concept of the index because my english is not good. The concept: *The number of species combinations *This

Hello, a user of one of my packages has sent me the following problem that apparently appears when loading the tcltk package. I'm guessing something (Tcl/Tk? R open scripting framework?) is not installed correctly... can someone please confirm or correct my guess? The OS is Mac 10.6.5. Thanks, Peter This is what I get: > ~ joseoter$ r > R version 2.12.0 (2010-10-15) > Copyright

Hi all, a user contacted me about a segfault when installing WGCNA package dowloaded from CRAN. I also see a segfault like that on certain installs of R. The package passes all CRAN checks, so presumably this has something to do with the R installation or environment. The R versions here are not the newest but I would guess that this is not an R version issue. I'm attaching two

Hello everybody, I am running dovecot 2.1.7 on Debian Wheezy on two servers with replication set up, MTA is postfix. The idea is to have a redundant mail system so that when one server fails, users can continue using the other server (failover of POP/IMAP through DNS redirection). Servers are called srv06 and srv07: Below is the dovecot config, both servers have identical config, only the

Hi Well, I think the title says it all!? I've looked through the documentation but I can't find a way of doing this.? The situation is that I have 4 series, say a, b, c and d.? Series a and c are plotted on the lh y axis, series b and d are plotted on the rh (secondary) y axis.? I've worked out how to do this. However, I need to plot series a and b a points (symbols only, no line),

Hi R Team!, ? We are opening a new start up soon, codinghoodies.com, we want to make coders feel stylish. ? Out of goodwill I wanted to ask you formally if I can have permission to use the standard R logo on the front of hoodies to sell? I have read your rules but wanted to ask as I feel a moral right to email you asking to show support and respect for the R project. ? If it makes it easier I

If you would like a 10 second R puzzle, you might like to think about this one: > g <- expand.grid(long = 130:140, lat = -(10:25)) > gp <- transform(g, x = long, y = lat) Error in transform(g, x = long, y = lat) : object "long" not found I don't expect this hasn't come up before, but I can't find mention of it. I suggest that to minimise this little

My guess: It I clear from the link that they can use the R logo for commercial purposes. The issue is what to do about the "appropriate credit" and "link to the license." How would I do that on a hoodie? Would they need a web address or something? -----Original Message----- From: R-help <r-help-bounces at r-project.org> On Behalf Of John Fox Sent: Tuesday, March 21, 2023

I have a few simple controllers doing plain, simple crud in a standard way. now it''s not very DRY to write a funtcional test for each controller, since they are all doing the same (apart from a few variable names, but that could be easily inflected or so). is there a way to do this? e.g. does inheritance work with tests, so i define a base test first, inherit my other tests and add a few

Dear R users, I am pleased to announce the release of a new packaged called `bcrm? (version 0.1), now available on CRAN. The package implements a wide range of Bayesian continuous reassessment method (CRM) designs to be used in Phase I dose-escalation trials. The package is fully documented and highlights include ? A choice of 1-parameter working models or the 2-parameter logistic model.

Hi All! We have just solved the problem. The error resides in the code placed in /samba-X.X.X/source/lib/util_getent.c between line 275 and 291 . By default, when you compile samba with solaris support, samba uses "getgrnam" function because of the "BROKEN_GETRNAM=1" in Makefile. This function is what's making samba going wrong. The soluction was to undefine

Hello, This may be a slightly rambling and inexpert question from point of view of the learned folks on this list - feel free to go and read something more interesting, but I am curious and a little alarmed about a recent event.
