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

Dear R users, I want to install the Rcmdr package in a Quantian linux machine, but, when i tried that, following commands appeared: ** building package indices ... * DONE (Rcmdr) The downloaded packages are in /tmp/RtmpuOikyk/downloaded_packages > library("Rcmdr") Loading required package: tcltk Error in firstlib(which.lib.loc, package) : Tcl/Tk support is not

There are many multivariate and taguchi testing tools in the market for php. Is there any such tool that for Ruby? Has any one had any experience with sitespect? I am not looking for A/B testing nor Google SIte Optimizer. Either Multivariate or Taguchi testing. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups

As you know, i have problem about Rcmdr in the 2.4.0 version of R, it can't be run properly in Quantian due to that Tcl/Tk does not support it. But, now, with helps from Dirk Eddelbuettel, problem was solved. The solution is just that reinstallation of R from debian packages not by compiling of 2.4.0 version source code. During the process, i noticed a srange thing, that is, if i start R in

Dear R users, Recenty i tried to install the R GUI of "RKward", but i think something is wrong. In installation, i used the command such like: root@quantian:/usr/lib/rkward# ./configure --enable-R-shlib or, root@quantian:/usr/lib/rkward# ./configure --enable-R-shlib --prefix=/usr/lib/kde3 due to in INSTALL file, it is said that use these commands if you don't have the libR.so

Dear R users, In last R News, a new package was appeared. EBimage image processing package seems so powerful. But in R News, it is used for the images of cells under microscope. So, i wonder whether there is anyone who use this package for materials science applications such as determination of mean diameter of particles, fibers or pores, estimation of porosity or covering factor. Sincerely...

Hi I am trying to generate a design using Algdesign and came across terms of "exact design" and "approxiamte theory design", I did not find a reference to explain what they are, could some one shed some light about this on me? Another question is, I want to measure the main effects and at least two interactions, variables are factors, how do I ensure this in formula,

Hello, we are needing to generate optimal (Fractional) designs for discrete choice applications, where we will be using logistic regression or multinomial logit as the modeling technique. It looks like optFederov, in the AlgDesign package may work, but not sure if this algorithm works when the variable of interest is binary or nominal? Anyone who are experts in this area, anyone interested

Dear developeRs, I have not found anything recent about how to link to a vignette or other documentation from within Rd-files. Is this now possible with the new help system ? For example, I would like to link to the file AlgDesign.pdf provided within the doc directory of package AlgDesign. Thanks for any suggestions, regards, Ulrike -- View this message in context:

Hi, I am wondering how I should interpreate the output of optFederov() in AlgDesign. Specially I want to know what is $D, $A, $Ge and $Dea, which one I can use as an efficiency to say how good the optimal design is. I only know when a orthogonal design comes, $D = 1. I red the pdf document -- vignette("AlgDesign") [Just type: vignette("AlgDesign") in R, you will get

Dear DevelopeRs, in continuing with my suite of packages on experimental design, I am stuck with an issue that appears to be related to package AlgDesign - I have tried to get it solved by Bob Wheeler, but he seems to be stuck as well. Whenever AlgDesign is loaded, some of my code does not work any more. For example, in a fresh R session: require(DoE.base) fac.design(nlevels=c(2,6,2))

Dear r-helpers, Could you please help me solve the following problem: When I run require(AlgDesign) trt <- LETTERS[1:5] blk <- 10 trtblk <- 3 BIB <- optBlock(~., withinData = trt, blocksizes = rep(trtblk, blk)) In response to the last command, R complains: Error in optBlock(~., withinData = trt, blocksizes = rep(trtblk, blk)) : object ".Random.seed" not found The

Hi, I have some problems when using AlgDesign->optFederov() generating designs. I have 6 variables, all factors. 3^2 and 4^4, I want to have a design that can take care of main effects and two interactions within 2 pair of variables v3-v4 and v5-v6, the following is the code ################ require(AlgDesign) set.seed(1) levels = c(v1=3,v2=3, v3=4,v4=4,v5=4,v6=4)

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)
