I'm curious whether this actually solves the problem. I understand how this assists with reproducibility of packages, but the R software itself is updated frequently, as is briefly noted in the preamble to this document. Indeed, the release notes [0] are fairly transparent about the relatively long list of changes. Given this, it almost seems more dangerous to imply through this package that a particular date's results are reproducible, since unless the user has the same version of R, they may see different results anyway.
