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 xemacs-info-21.4.13-35 xemacs-packages-el-20030629-37 xemacs-21.4.13-35 xemacs-el-21.4.13-35 xemacs-packages-info-20030629-37 xemacs-packages-20030629-37 ess-5.2.0beta3-1.i586.rpm

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

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

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: > summary(chemdata) site_id.sample_date.param.quant

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 Stefan

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

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

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 the rows of

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

Hi All: Greetings, and best wishes from the festive times here at Kolkata, India -- the time of Durga Puja celebrations. I seek your advice as I try plotting lines for my data.

The current proposed list of side sessions are: - OpenCL (and similar

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 shapiro.test()

Hallo ! Ich habe versucht Rcmdr unter MacOSX 10.4.5 zu installieren. RGui zeigt an, dass tcl/tk laufen. Bei Aufruf von Rcmdr friert R jedoch komplett ein. JGR zeigt im Paketmanager dagegen an, dass tcl/tk nicht gestartet werden konnte und spuckt folgende Meldung aus: > library(tcltk) Loading Tcl/Tk interface ... Error in fun(...) : no display name and no $DISPLAY environment variable

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

Hi Sorry, my first post was in German. I tried to get Rcmdr running under MacOS X 10.4.5. While RGui pretends that tcltk is running, starting Rcmdr freezes R completely. Instead, JGR which gave me the following results: > library(tcltk) Loading Tcl/Tk interface ...

Recently, we made a switch from 1.9.18 to 2.0.3. Under 1.9.18, we had local master turned off to prevent a browser election war. However, under some network configurations, (where the system was alone on a Workgroup), the system would, quite appropriately, not appear in the network neighborhood. So for 2.0.3 we changed the config file to allow election participation (local master = yes).

Hi R experts, I am interested on the effects of two dietry compunds on the growth of chicks. Rather than extracting linear growth functions for each chick and using these in an analysis I thought using ReML might provide a neater and better way of doing this. (I have read the pdf vignette("MlmSoftRev") and "Fitting linear mixed models in R" by Douglas Bates but I am not
