Take a look at the blockrand package, it may do what you want.
> library(blockrand) #after installing
> myrand <- blockrand(40, block.sizes=4)
> myrand
hope this helps,

Subject: [R] random permuted block randomization
Hi,
I am very new to R. Just started yesterday. I have to generate a sequence of
40 random treatments using permuted block randomization with a block size of
8. Then I have to plot moving averages for the resulting sequence. I have
tried the sample function but I dont know if wht i did is right or not
> sample(c(1,1,1,1,2,2,2,2),8)
Any ideas please?
