Eehm; that has a wrong date (or then it would not be pre-alpha): I've always entertained the prehistoric directory of R sources at and its oldest file is

         Name	           Size    Date        
         R-0.1alpha.tar.gz 861464  Feb 12 1996 

(which will be 10 years coming Sunday -- what a jubilee!!) So, even that is not pre-alpha; and yes, that was a bit before CRAN existed.

Now to the pre-alpha history. I've digged some more and found

  1. that the mac file mentioned above would have correct date 'Nov 6 1995' (at least that's the date I saved when I looked at the Auckland FTP server through Emacs ange-ftp).
  2. The oldest stuff that I have is all from 1995; The source I (think I) had first used is dated June 20 1995; notably the R-unix-src.tar.gz with accompanying README and INSTALL files (There was also ./win subdirectory which I did not use, with files all from July 15, 1995; AFAIK done by Robert Gentleman)

 I've now put a bit of these oldest files into

3) I've kept an e-mail that Ross had sent me on July 28 with

   two small patches to the (June 20) sources.    

   Yes, chances are pretty high that I was the first one outside    of the Auckland(NZ)-community to actively use R.  

Note it might be interesting to find even older sources, but that would most probably have to be by Robert and Ross (or a sysadmin at Auckland).
