The package blockrand is now available on CRAN.

This package aids in doing block randomizations for clinical trials or
other situations where subjects or experimental units arrive over time
and need to be randomized one at a time.  The block randomization keeps
the number of subjects in each arm of the trial fairly balanced.

The package also includes a plot function that creates a pdf file of
randomization cards that can be put in envelopes and given to a study
coordinator for the actual assignment to treatment as subjects are

Comments, suggestions, and contributions are welcome and appreciated.
