Hello Allie: Reproducibility of the results is an important question. Personally, i do not believe much to automated solutions, although i may be wrong. When i store a result of a simulation for future reference as an ".rda" file, then the script includes into it an object "identification", which contains seeds, a critical function used in the simulation and also a package and R version. The last two things may be obtained for example as R.version.string library(help=mvtnorm)[[3]][[1]][3] Up to now, i did not really needed these things, so i also do not know, whether they are sufficient.
