Stats in the Wild

I’m trying to calculate a net reclassification index (NRI) using the ‘nricens’ package.  I downloaded it from CRAN and tried to start using it.  However, I couldn’t quite get it to work and I kept getting strange errors.  So I went the documentation, and this just made me more confused because it seemed that the documentation didn’t match the functions.  After some time (too long probably), I realized that the version in the CRAN repository (1.1) was not the same as the one for the documentation I was reading.  So, I guess I am confused why there is documentation on the cran website for version 1.2, yet version 1.1 is the version in the repository.

Cheers.
