[R] Package or packages for randomization in a clinical trial

[John Sorkin]

Can anyone recommend a package that can be used to randomize subjects? I am looking for a generalized package, or several packages that can accomplish 
unrestricted randomization (i.e. simple random assignment)
restricted randomization including stratified randomization, blocked randomization, and adaptive randomization.
Thanks,
John
