I apologize for adding this so late to the "SAS or R software " thread. This is a question, not a reply, but it seems to me to fit in well with the subject of this thread.
I would like to know anyone's experiences in the following two areas below. I should add I have no experience myself in these areas:
1) Migrating from SAS to R in the choice of statistical software used for FDA reporting.
(For example, was there more effort involved in areas of documentation, revision tracking, or validation of software codes?)
FDA has no requirements. They accept Minitab and even accept Excel. Requirements are to be a good statistician doing quality reproducible work for its own sake.
2) Migrating from SAS to R in the choice of statistical software used for NIH reporting (or other US or non-US) government agencies) .
No issues.

I find myself using R more and more and being continually amazed by its breadth of capabilities, though I have not tried ordering pizza yet. I use SAS, S-Plus, and, more recently, R for survival analysis and recurrent events in clinical trials.
