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

Thanks, John John, Take a look at the 'blockrand' and 'crossdes' packages on CRAN. If you need something beyond those, it is not overly difficult to write functions in R to do this.
