similar to: OT: Compiling EMMIX

Are there any S-Plus or R libraries/packages that do Finite Mixture Analysis following the algorithms similar to those implemented in Geoffrey MacLachlan's EMMIX program? Thanks. Dr. Marc R.

Thanks to John Day, Tom Richards, Mike Prager, Thomas Lumley, and Goran Brostrom, for various helpful suggestions that finally allowed me to get EMMIX compiled on my Linux (and my Windows) machines. The problem was a simple case-sensitivity issue concerning a single file, which I had correctly downloaded but named using the wrong case ("emmix.max" instead of "EMMIX.max").

I just updated rpart to the latest version (3.1.0). There are a number of changes between this and previous versions, and some of the code I've been using with earlier versions (e.g. 3.0.2) no longer work. Here is a simple illustration of a problem I'm having with xpred.rpart. iris.test.rpart<-rpart(iris$Species~., data=iris[,1:4], parms=list(prior=c(0.5,0.25, 0.25))) + ) >

I ran across this error the other day while using lm(). I confess that I haven't used it for awhile and haven't been tracking the changes between versions of R. However, the piece of code below is a tiny modification of the example in the help file for "lm". I just separated the commands apart for clarity. A similar piece comes from the help file for

Probably wrong group for this, but a quick question. I've just switched from emacs to Xemacs. In reinstalling ESS 5.1.19 I keep getting the following error when loading Xemacs: "Error in init file: Symbol's function definition is void: w32-using-nt" I've debugged the ess-site.el file, which is where the error originates from. The line causing the difficulty is:

What is the generally accepted way to put certain math symbols into plain text email? For example, how does one convey the "is exactly equal to", "is approximately equal to", and "delta" symbols in a standard text-based (e.g. Courier) font? Dr. Marc R.

Is there any effective way to get distinct geometric plotting symbols and colors for plots involving more than 25 groups? Thanks. Dr. Marc R.

I've created a bunch of postscript trees (post.rpart), which I subsequently edit in Adobe Acrobat 4.05 (I need additional labelling that isn't easy to add with R). After editing the labels and annotations using Acrobat, I then export the file to Adobe's .eps format so I can insert the picture into a Microsoft Word 2000 document. The .pdf file distilled from the .ps file is

Our lab just picked up a G4 Powerbook (1 GHz, 1GB RAM, OS X 10.2.6). None of us have any experience with Macs but for various reasons we need to have one around for development. In any case, we've installed fink, all the Apple Developer Tools and the Dec2002updater to gcc 3.3. We're now trying to compile R 1.7.1 without too much success. First we had to get g77, which turned out to

Hi, Before I write code to do it does anyone know of code for fitting mixtures of multivariate-t distributions. I can't use McLachan's EMMIX code because the license is "For non commercial use only". I checked, mclust and flexmix but both only do Gaussian. Thanks Nicholas

Forgive what may seem to be a trivial question/problem. Below is some simple R 1.2.1(Windows) code with output. > summary(mammals, digits=10) Name Body.Weight Brain.Weight Red Fox :1 Min. : 3.0 Min. : 26.0 Pig :1 1st Qu.: 35.5 1st Qu.: 138.5 Man :1 Median : 100.0 Median : 406.0 Kangaroo:1 Mean : 761.2 Mean :1000.0 Jaguar :1 3rd

In my research area, researchers are very stingy about sharing data. In fact, they are frequently downright secretive about these morsels. Typically, we get fed a diet of summary statistics and the assurance that the data are *normal* without any necessary documentation that they really are. With that as background and assuming that the data really are normal, is there any way in R (or any

I just downloaded version 1.0.0 and several binary libraries (VR, rpart, norm, stataread) - WinNT version. I then converted a file from Stata 6.0 to R format by using the stataread library. The file converts perfectly and I was able to use the VR function lda on the dataframe without difficulty. I then tried to use the same dataframe with RPART. The model statement:

Running 1.4.1 (Windows) under Windows XP Pro. Have had no difficulty for several weeks since moving to the new OS. Today, while checking the behavior of my mouse, I loaded Rgui as usual. I then immediately tried to exit the program. Upon exiting, I got the following message: Error in save.image(name) : image could not be renamed and is left in .RDataTmp I can move the .RData file to any

At the risk of starting a holy war, I'd like opinions on the "best" current Linux distribution to run "out of box" with current versions of R. I note rpms for various versions of RedHat, SUSE, Mandrake, and Debian. I've had experience with RH 7.1 & 7.2 and it hasn't been entirely pretty. I understand that 7.3 is a bit "better", but have also

A week or so ago, I reported a problem on my new Windows XP box getting R 1.4.1 and R 1.5.0 (development from BDR's site) to save the .RData file upon program exit. Specifically, either clicking on the "X" in the GUI or invoking q() from the command line produced the following error: Error in save.image(name) : image could not be renamed and is left in .RDataTmp1 After some

I've been using the package rpart with R 1.3.0 for Windows to produce simple classification trees for some measurement data from paleontological specimens. Both the rpart documentation and the output confirm that the program produces splits on continuous data that leave "holes" in the data. It is probably of little practical importance, but is there a reason why the binary

I've been combing through logs I keep of all my activities. I've found a possible correlation between the save.image() problem I'm having and one particular event. My system has a rewriteable DVD drive. I keep a 4.7 GB DVD/RW disk in the E: drive and have a system scheduler synchronize the contents of the g: drive with the e: drive every Friday night. Interestingly, both times

At the risk of being flamed for mortal stupidity, I'm trying to figure out what could have possibly changed (at my end almost certainly) that make Brian Ripley's posts (in particular) not show up on my mail server (at least not on the one where I receive my email). All my email comes to a central university server from which it is forwarded to several different places where I can get
