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 ftp://stat.ethz.ch/Software/R/alpha/PreHistoric/ 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 ftp://stat.ethz.ch/Software/R/alpha/PreHistoric/pre-alpha/ 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).
