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)) require(AlgDesign) fac.design(nlevels=c(2,6,2)) > Error in...

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...

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 a...

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 in consulting with us in this topic (if so, email me we can arrange)? Or can confirm/deny optFederov can work in the discrete case...

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 docume...

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: http://old.nabble.com/Link-to-pdf-documentation-from-other-package---tp26405139p26405139.html Sent from the R devel mailing list archive at Nabble.com.

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(v...

AlgDesign is a new package for calculating algorithmic experimental designs. It will calculate both exact and approximate designs for a variety of criteria. It will handle very large designs. It will also block designs in a variety of ways, including split plotting. You should find it at least as capable as...

Can anyone explain why AlgDesign's expand.formula help and output differ? #From help: # quad(A,B,C) makes ~(A+B+C)^2+I(A^2)+I(B^2)+I(C^2) expand.formula(~quad(A+B+C)) #actually gives ~(A + B + C)^2 + I(A + B + C^2) They don't _look_ the same...

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 the...

Dear R Users, If it is possible, i would like to learn whether a R package that can be used for Taguchi design is available. Sincerely -- Ýbrahim Mutlay [[alternative HTML version deleted]]

...nt, and which not. For example: I can select of course my main effects, but also if I want to see interaction A:B, B:C, A:B:C,but not A:C. This was very interessting as you can end up with fewer runs, especially in cases of 10 factors with 2-3 levels. Is there a way to do this with R? I found the AlgDesign package, and I tried optFederov and optMonteCarlo, as you can set a formula (like: A+B+C+A:B+B:C+A:B:C). But while using this, I end up with to much runs, so I have some residuals. And sometimes I cant get the right interactions from my design. So: are there better ways to achieve the right design?...

Hi, Does anyone know how to generate block designs using the AlgDesign package? I have a experimental design with 1024 combinations and need to reduce it. Thanks! Edson [[alternative HTML version deleted]]

Dear R users, I have used the AlgDesign package to construct a D-optimal exp. design from a file containing a set of allowed runs. The code for the optFederov call is below: #Using optFederov ------------------------------ library(AlgDesign) options(contrasts=c("contr.sum","contr.poly")) file<- read.table(&qu...

Hello everyone, I am trying to use the 'find.BIB' function to construct a balanced incomplete block design. When I ran the example given in the help file (find.BIB(10,30,4)), I obtained the following error message: Error in optBlock(~., withinData = factor(1:trt), blocksize = rep(k, b)) : object ".Random.seed" not found I investigated what the optBlock

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
