OT: Compiling EMMIX
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

rpart 3.1.0 bug?
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)))

ESS 5.1.19 w/Xemacs 21.4.6
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:

Math symbols in email - not completely OT
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?

OT: ps -> eps -> MS Word
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

Below is some simple R 1.2.1(Windows) code with output.

Warning - Naive Question Alert
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

Bootstrp help
Hey,
I have a set of data and want to use Bootstrap
method to estimate some pararameters.
So does anybody know if there are such
functions in R to achieve this?
Thanks for your points.

Help for Linear Discriminant Analysis
Dear colleague,
I'd like to compute linear discriminant analysis, using R. In the book Modern applied statistic with Splus (Venables & Ripley, p. 396), lda function is used. Could you tell me where I can find this function? At what site, can I download this library ?
Thank for your help.

A Very Trivial Question
Hi,
This is a very trivial question, and I do not know why I cannot remember
the answer at all!
How does one get the entire system information (which OS, R
version....etc) using an R command?
Thanks,
Kevin

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

Thanks for help on EMMIX
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").

save.image() error
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:

R version 1.4.1 is released
I've rolled up R-1.4.1.tgz a short while ago. This is a patch upgrade,
fixing the most important bugs that cropped up after the 1.4.0 release.
A set of recommended packages which have been tested with R-1.4.1 has
been bundled up. Binary distributions are expected to include these
packages.

round() seems inconsistent when rounding 5s
It may be my lack of unerstanding, but round() seems to me to give
inconsistent results when rounding 5s as in the following examples?
> round(1.45, 1)

> round(2.45, 1)
[1] 2.5 # shouldn't this be 2.4?
> round(1.05, 1)

and signif():
> signif(2.445, 3)

How to do linear regression with errors in x and y?
QUESTION: how should I do a linear regression in which there are
errors in x as well as y?
SUPPLEMENT: I've seen folks approach this problem by computing
eigenvectors of the covariance matrix, and that makes sense to me.
But I'm wondering if this has a "pedigree" (i.e. if it makes sense to
folks on this list, and if it's something that has been published, so

ps/eps/Word
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
