Hi R HELP, I consider the 2^3 factorial experiment described at page 177 of the book Statistics for Experimenters: Design, Innovation, and Discovery by George E. P. Box, J. Stuart Hunter, William G. Hunter (BHH2). This example use the following data in file BHH2-Data/tab0502.dat at ftp://ftp.wiley.com/ in /sci_tech_med/statistics_experimenters/BHH2-Data.zip run T C K y 1 1 -1 -1 -1 60 2

Dear R fans, I am preparing a lecture discussing the paper of Wilkinson and APA Task Force on Statistical Inference (1999, American Psychologist, 54, 594-604.) I'd like to demo their Figure 3B (p. 602) with R. That is to add plotMeans(...) with dots of BHH2::dotPlot(...) . Is there any elegant script to do the job? Thanks --------------- LI, Xiaoxu

Dear Madame, Dear Sir, I am able to obtain the coefficients from a 'summary' of 'lm', but NOT from a 'summary' of 'aov'. The following example shows my steps. ## Initialize rm(list = ls()) # remove (almost) everything in the working environment utils::data(npk, package="MASS") # get data model <- yield ~ block + N*P*K ## Using lm npk.lm <-

Dear R users, I have the following problem: I have a table in ASCII-format, separated with commas. I can read it as long as no field contains a comma itself. If one does, read.table doesn't function even though that field is double-quoted. Ex.: File "test.csv": Name,Strasse,PLZ Jsaac,Gossauerstrassee 29,9100 Roth-Bernasconi,"20, ch. des Fauvettes",1212 adressen <-

Dear R experts, Can R make an usual dotplot just like Minitab and other softwares? I have the following data, and can use dotchart to graph a dotplot: y=c(2.873438152e-01, -8.732895642e-01, 4.579001889e-01, 1.047395204e+00, 8.491182299e-02 , -1.938007105e+00, -1.273708343e+00, 9.848010588e-05, 7.238490734e-01, -1.490552717e+00) dotchart(y, xlab="10 observations from

Hi, I know this is not a 100% Asterisk question, but is there anyone who has the Flash Operator Panel working with Asterisk 1.6?? In asternic.org there is a version that show call status but you cant make transfers or originate a call. Has anyone fixed the op_server.pl file to fully work with Asterisk 1.6??? Thank you very much, Pablo Bernasconi -------------- next part -------------- An HTML

I am now writing an R code to do the systematic permutation test and the random permutation test. And I encountered a couple of problems which I cannot figure them out. At first, whenever I type "permtest" in my R2.6.1, it always shows:"there is no such a function", I tried again and again and eventually I found I have to use "library (BHH2)" before I use

All, I have just returned to R after a decade of absence, and it is good to see that R has become such a great success! I'm trying to bring Design of Experiments into some aspects of software performance evaluation, and to teach myself that, I picked up "Experiments: Planning, Analysis and Optimization" by Wu and Hamada. I try to reproduce an analysis in the book using lm, but

Afternoon everyone, I''ve spent the last week or so looking at all the experimental design packages I can find in R. AlgDesign, design.conf and BHH2 being the best one I could find. Unfortunately none of these do a particularly good job for complex designs, in particular for conjoint or discrete choice. (or perhaps they do, and I can''t make them work correctly)

Dear R People: I will be teaching an undergraduate Design of Experiments class in the Spring Semester. It will be very much an applied course. My question, please: has anyone used R for a course like this, please? I've tried Rcmdr for a regression course and just plain command line for a time series course. Should I use Rcmdr, or teach them to use the command line, OR is there something

Hello, I need to be able to send a DTMF to an existing channel remotely. So I made a php script to do such with the Manager command PlayDTMF.

Hi, I need to integrate my Asterisk with a Nortel Meridian 11, but I can?t use PRI, Analog lines, etc. It has to be via SIP protocol, and there is few information about this type of integration. Could someone please help me?? Thanks, Pablo -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi R help, What is the best way to plots surfaces in 3 dimensions? I also have the following availability problem with "plot3d" and "scatterplot3d", and "wireframe": install.packages("scatterplot3d") Warning: unable to access index for repository http://cran.ch.r-project.org/bin/macosx/leopard/contrib/2.10 Warning message: In getDependencies(pkgs,

Dear r-helpers, I wonder if you can figure out why the following is working: ******************************************************************** > sessionInfo() Version 2.3.1 (2006-06-01) powerpc-apple-darwin8.6.0 attached base packages: [1] "tcltk" "methods" "stats" "graphics" "grDevices" "utils"

Hi, I want draw a dotPlot. All works fine: (Seq <- matrix(c(1, 1, 6, 1, 2, 2, 5, 4, 3, 3, 4, 3, 4, 4, 3, 2, 5, 5, 2, 5, 6, 6, 1, 6), ncol = 6)) dotPlot(Seq[1,], Seq[2,], main = "Sequenz 1 und Sequenz 2", asp = 1) Is there a way to draw a small diagonal, begin at (0/0) to (6/6) (perhaps in red??) or must I use gimp? I have many dotPlots, so it is fine if R can do this. Thanks Joerg

Hi, We were wondering how we could make a stacked frequency diagram such as this one: http://msemac.redwoods.edu/~darnold/math15/liz.pdf We don't necessarily need the shaded "balls", other characters would be fine, such as stacks of x's. David

L.S. We would like to generate fractional design for a conjoint analysis. For example we would like to reduce 2x2x2x2x3 --> 12-16 profiles. We tried the R-package "conjoint" and we found an article which describes how to make fractional design for these kinds of studies with Algdesign: http://tolstoy.newcastle.edu.au/R/e10/help/att-8876/DCE_with_R.pdf However, the generated

I'm starting to do a fair amount of DOE in my day job and need to generate full- and fractional-factorial designs. One of the things I'd like to do is generate all possible interaction effects, given the main effects. I've been searching through the documentation, packages and mail list archives, but the closest I can find are combin() in package combinat and combine() and

Dear R-users, I want to know if there is a package that allows to define different experimental designs (factorial, orthogonal, taguchi) and to compare them. I don't found one in the R-web site, but it is possible I missed it! Thank you in advance Sincerely, Marc

It seems people are reinventing the wheel here: The goal is to generate all combinations of 1:n of size k. This (typically) results in a matrix of size k * choose(n,k) i.e. needs O(n ^ k) space, hence is only applicable to relatively small k. Then alternatives have been devised to generate the combinations "one by one", and I think I remember there has been a quiz/challenge about 20
