[Rd] The case for freezing CRAN

[Therneau, Terry M., Ph.D.]

There is a central assertion to this argument that I don't follow:

> At the end of the day most published results obtained with R just won't be reproducible.

This is a very strong assertion. What is the evidence for it?

  I write a lot of Sweave/knitr in house as a way of documenting complex analyses, and a 
glm() based logistic regression looks the same yesterday as it will tomorrow.
