Hi all, I need to design an experiment very similar to the design described in the AlgDesign vignette on page 44. When I run the code on the vignette, I get the following error:
> library(AlgDesign) > Rep<-gen.factorial(3,1,factor=1,varName="Rep") > Block<-gen.factorial(3,1,factor=1,varName="Block") > firstDesign<-optBlock(~.,within=Block,whole=Rep,blocks=rep(3,3)) Error in optBlock(~., within = Block, whole = Rep, blocks = rep(3, 3)) : All variables seem to be block variables This is my sessionInfo() R version 3.1.1 (2014-07-10) Platform: x86_64-pc-linux-gnu (64-bit) locale: [1] LC_CTYPE=en_US.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_US.UTF-8 LC_COLLATE=en_US.UTF-8 [5] LC_MONETARY=en_US.UTF-8 LC_MESSAGES=en_US.UTF-8 [7] LC_PAPER=en_US.UTF-8 LC_NAME=C [9] LC_ADDRESS=C LC_TELEPHONE=C [11] LC_MEASUREMENT=en_US.UTF-8 LC_IDENTIFICATION=C attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] AlgDesign_1.1-7.3 loaded via a namespace (and not attached): [1] compiler_3.1.1 tools_3.1.1 I searched this error on rseek.org and the archives and found nothing that was helpful. Any help would be appreciated.
