This is to announce an updated version of the blockrand package has been uploaded to CRAN. The blockrand package is used for creating randomizations for clinical trials or other studies where random assignments are made one at a time. It implements the ideas of randomizing within blocks so that the numbers of subjects in each group remain fairly balanced (but allows for unbalanced blocks to make anticipation of future allocations more difficult). It also includes a function to print randomization cards (creates a pdf file) that can be put into envelopes for a study coordinator to use to assign subjects to treatments. -- Gregory (Greg) L.
