How to configure ess-5.2.0beta3-1.i586.rpm, Xemacs and SuSE 9.0?
I'm trying to get R and ESS to work with Xemacs on a newly installed
SuSE 9.0 system. Is some setup required beyond installing the rpms?
I've installed the Xemacs packages from SuSE

par() in .Rprofile
Dear all
I installed new version (from binaries) and I noticed that
par(bg="white")
which I have in my .Rprofile causes error message on startup
But if I issued this command immediately after startup everything worked as
expected. I did not see any note in changes file or elsewhere.
Should I specify white background in .Rprofile differently?
Or is there some other recommended way

A hint to start ESS-xemacs
I'm trying to use ESS & xemacs under debian linux testing and KDE.
My problem is that I didn't find any document in the internet explaining a
**step by step** session with R and xemacs.
The (wrong) procedure I follow (to no avail!) is:
1) I start R in a terminal window;
2) I start xemacs and open a file with the extension .R (test.R);
3) I issue M-x R RET and I can see an Rd new

Descriptive Stats from Data Frame
I don't find how to do what I need to do in Dalgaard or 'R Cookbook', so
I'm asking here.
I have a data frame with water chemistry data and I want to start
exploring these data. There are three factors (site, date, chemical)
associated with each measurement. The data frame looks like this:

(no subject)
Hi all,
I am looking for a clever way to create the following graph using R:
I got information on the shares of some subgroups over time (summing up to 1 in each year). The graph I want to create should display the development of the individual shares over time by shading rectangulars for each share in a different color.
Is there a clever of doing this?
Thanks for your help

Total least squares linear regression
Dear all,
After a thorough research, I still find myself unable to find a function
that does linear regression of 2 vectors of data using the "total least
squares", also called "orthogonal regression" (see :
http://en.wikipedia.org/wiki/Total_least_squares) instead of the
"ordinary least squares" method. Indeed, the "lm" function has a

"subscript out of range" message
Hi All:
I was recently working with a dataset on arsenic poisoning. Among the
variables in the dataset, I used the following three variables to produce
crosstabulations (variable names: FOLSTAT, GENDER, ASBIN; all three were
categorical variables, FOLSTAT denoted follow up status for the subjects and
had seven levels, GENDER denoted sex (two levels: male,female), and ASBIN
denoted binarized

Inquiry About R Packages for Specific Research Areas
Dear R Support Team,
I hope this email finds you well.
I am writing to inquire about the specific R packages that would best suit
our academic research project, which involves analyses in various fields.
We are particularly interested in the following areas:
Epidemiology Analysis: We are aware that packages like epiR, survival, and
epitools exist for epidemiological analysis. Could you please

Fisher Test in R
Suppose we have the following data set:
Men Women
Dieting 10 30
Non-dieting 5 60
If I run the Fisher exact test in R then what does alternative = greater (or
less) imply? For example:
mat = matrix(c(10,5,30,60), 2,2)
fisher.test(mat,alternative ="greater")
I get the p-value = 0.01588 and odds ratio = 3.943534. Also, when I flip

multiple plots using summary in rms package
Dear All,
I wonder if someone can point me in the right direction here. I'm working
with the rms library, R 2.9.2 under Windows XP.
I'm trying to arrange two plots side by side for a colleague. mfrow or
mfcol do not seem to work, however, so I am obviously missing something
important. I know that there have been changes in the graphics from Design
to rms, but am just not sure where to

shapiro.test() output
R Users:
My question is probably more about elementary statistics than the
mechanics of using R, but I've been dabbling in R (version 2.2.0) and
used it recently to test some data .
I have a relatively small set of observations (n = 12) of arsenic
concentrations in background groundwater and wanted to test my
assumption of normality. I used the Shapiro-Wilk test (by calling

tcl/tk - Problem unter MacOS X / X11
Hallo !
Ich habe versucht Rcmdr unter MacOSX 10.4.5 zu installieren. RGui zeigt

JGR zeigt im Paketmanager dagegen an, dass tcl/tk nicht gestartet werden

Can lmer() fit a multilevel model embedded in a regression?
I would like to fit a hierarchical regression model from Witte et al.
(1994; see reference below). It's a logistic regression of a health
outcome on quntities of food intake; the linear predictor has the form,
X*beta + W*gamma,
where X is a matrix of consumption of 82 foods (i.e., the rows of X
represent people in the study, the columns represent different foods,
and X_ij is the amount of
