An alternative (and arguably more useful) strategy would be to cache results of each computational step, and report when results differ upon re-execution with identical inputs; if you cache sessionInfo along with each result, you can identify which package(s) changed, and begin to hunt down why the change occurred (possibly for the better); couple this with the concept of keeping both code *and* results in version control, then you can move forward with a (re)analysis without being crippled by out-of-date software. -Aaron -- Aaron J.
