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)

attached base packages:

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.
