Varying results of package checks due to random seed
...n which case the seed is set based on the current time and process id, with an obvious possibility of results varying from run to run. In the current development version of pqR (in branch 19-mods, found at https://github.com/radfordneal/pqR/tree/19-mods), I have implemented a change so that if the R_SEED environment variable is set, the random seed is initialized to its value, rather than from the time and process id. This was motivated by exactly this problem - I can now just set R_SEED to something before running all the package checks. Radford Neal
