Not to detract from John's very interesting work, but
there is a problem with citations as a measure of
penetration.  When R totally succeeds, there will be
no citations.  How many citations are there for Excel?
However, for the moment, citations are probably a
pretty good measure.


Using traffic on R-help is even more problematic in
this regard.  Each question sent to R-help is clearly a
failure (of documentation) rather than a success.  Plus,
unlike citations, there is a limit to the capacity of a mailing
list -- exponential growth in messages on a single list is
clearly unsustainable.  To look at such statistics it would
make sense to sum over all the R mailing lists.

Tangential: In the early days of S-news it was apparent
that traffic was a proxy not for total users but for new users.

Clarification: Saying that a question to R-help is a failure
of documentation is neither denigrating R documentation nor
letting questioners off the hook when the answer to their
question is clearly and prominently documented.  I'm saying
that for whatever reason the questioner found it less costly
to post a question than to find the answer in the documentation.
Cost functions vary.

So what is the answer to the question: "Can success continue"?

I suspect that R is now so firmly entrenched that it will
inevitably continue, in one or other incarnation, for a long
time to come.  The negative factors that John Fox lists
will surely, in time, make some changes inevitable.  Will
these come from force of circumstance rather than from
conscious planning?

In an August 12 message I posted details of R citation rates that
I had gleaned, following a lead from Simon Blomberg, from Web
of Science.  This, or some such measure, seems to me important
as giving a handle on the penetration of R into statistical
application areas.

The numbers I obtained [I&G = Ihaka & Gentleman 1996; RSTAT is
the citation suggested by citation()] were:

I&G: 1998=4,
          1999=15,
           2000=17,
           2001=39,
           2002=119,
           2003=276
RSTAT+I&G: 2004:68+455 = 523
                        2005:433+512 = 945
                        2006:1049+426 = 1475
                        2007:1605+410 = 2015
                        2008, (to ~Aug10):1389+255 = 1644

cit <- c("1998" = 4, "1999" = 15, "2000" = 17, "2001" = 39, "2002" =119,"2003" = 276, "2004" = 523,"2005" = 945,"2006" = 1475, "2007" =2015,

    "2008"=1644)

These will not be all that accurate; there will be omissions
and duplications.

Growth is close to exponential.

Hello everyone,

As some may know, today Google unveiled its 2001 search index [1]. I
was curious to see how was R like at that time, and was not
disappointed. Compared to today's main page [2], seven years ago the

page looked [3] a bit rudimentary, especially the graphic. (It iswortnoting that structurally the pages are very similar.) Whatdefinitely

changed is the `Contributed packages' section. Then R featured 29
contributed packages [4], while now it features 1500+ [5]. It was
surprising to realize the growth of R during the past seven years.

Many thanks for this, Liviu! One might also compare the mailing list
usage:

[R-help 1997]:   484 messages
[R-help 2001]:  4309 messages
[R-help 2007]: 26250
              1721+1909+2196+2145+2210+2309+
              2142+2246+2028+2711+2602+2031

So we now get more posts in a week than we did in the whole of 1997!

Those not present at the useR in Dortmund might want to skim JohnFox's talk


http://www.statistik.uni-dortmund.de/useR-2008/slides/Fox.pdf

(Actually, he did something at the end to avoid ending on a negative
note. Flipped back to one of the increasing graphs, I suppose.)
