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

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.

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.

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:

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))) + ) >

Thanks to all who offered advice on how to solve a loss of resolution problem involving ps from R, ps -> eps from Acrobat, and Word. It appears that this problem will need to be resolved inside R. If I try to add anything additional (more text, clipart embellishments) to a ps/eps file (using, say, Adobe Acrobat, PaintShop Pro, Powerpoint, or Adobe Illustrator), it gets placed as a

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

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

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'm running R 1.5.1 under Windows XP Pro. I haven't paid too much attention to the way R starts up until now. I've noticed that on all my Windows XP systems, Rgui.exe starts "maximized" despite having the shortcut properties set for it to run in a "normal" window. I've tried resizing the windows (I use MDI sessions) and then saving the workspace, but the

Just a quick followup to the query I posted yesterday. The default screen layout for the Windows version of R (1.5.1 currently) is MDI, which has the RGUI itself maximized over the entire screen, while the R console is in a smaller window inside the RGui. I asked whether there was some way at startup to change the amount of screen real-estate occupied by the RGui itself since this can be

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").

Sorry for the off-topic post, but there is such a wealth of knowledge here that I thought someone might have suggestions. Geoff MacLachlan and David Peel have a program - EMMIX - available for mixture modelling. It is only available as FORTRAN source code and is "downloadable" from Geoff's site. The code is reputed to run on Unix machines and is compilable according to

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

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

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

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

I have in my inbox a note saying books are expected in early August. However, for R users there is relatively little advantage in the third edition, except that almost everything works unchanged. The real advantages of the third edition are for users of S-PLUS 5.x and 4.5/2000. > From: Marc R. Feldesman > To: guido at hal.stat.unipd.it; 'Guido Masarotto '; 'Maria Wolters '
