[R] package:AlgDesign and .Random.seed

[Michael Kubovy]

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 documentation of optBlock() in AlgDesign doesn't say that I  
needed to set .Random.seed. I thought it was initiated automatically  
at the beginning of a session. What am I missing?
