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).

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 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

...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 "permtest", though it make me very glad, the question is It just works for two samples situation, but does not work for 3 samples at all. Well, What I want to do is to use both the systematic permutation and the random permutation to test H0:µA= µB =µC Where, say A&lt...

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) Specifically, the problem is that none of them optimise the design...

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

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

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

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

...shows # DATE WRITTEN: 14 April 1994 LAST REVISED: 10 July 1995 # AUTHOR: Scott Chasalow OTOH, people have since reinvented the wheel quite prolifically: There's combinations() in gtools {based on Bill Venables' code from R News 1/1}, combs() in CAtools, subsets() in BHH2, and nchoosek() in vsn (bioconductor); then 'fwd.combn' in package "forward" which states explicitly that it is Scott's combn() renamed.. I stopped searching for more, and I've made sure all these 6 functions compute the same thing, at least in the most simple case. After...

Hi, i need to create a fractional factorial design sufficient to estimate the main effects. The factors may have any number of levels, let's say any number from 2 to 6. I've tried to use the library conf.design , but i cannot figure out how to write the code. For example, what is the code for a design with 5 factors (2x3x3x5x2) and only main effects not confounded? thanks in advance!

Hi all, Does anybody know if it is possible to build a fractional factorial design in R? That is, suppose that we want do design an experiment with 3 factors with 2, 3 and 3 levels, respectivly. However we want to consider, let's say, only 6 from all possible level combinations. Does R design such experiment? Thanks in advance, Caio [[alternative HTML version deleted]]
