Block randomization

[Polina]

Hello everyone!

Does anyone know packages or functions on R with which you can do block randomization with allocation ratio 3:1?

I haven't done this in R yet, but I have done it in the past, block and varied block size randomization in SAS. Where code is available online if you want to rewrite it into R. I would be interested to see if you find a relevant package - which it would be difficult to imagine a package doesn't exist.

Thank.

In R you may do block randomization using blockrand function from blockrand package.
