Hi R community,
These days, I am writing some functions to work with 2-ways frequency
tables ; you know all this tuff about measures of association: Chisq and
derived (phi, cramer's v), tau b, tau c, somer's d and so on.
So I consider all those functions could be gathered in a single R file, as
they are coherent and dealing with the same problem / objective (analysis
of crosstables). Nervertheless, I wouldn't say there is here enough stuff
to juystify the creation of a library. First, there is here few material,
second it is not enough to cover the practical problem; which should be the
goal of a library.
In fact, I have also lot of others splitted files with R code suitable for
different purposes. And I could easily imagine I am not the only one among
R programmers... And at the end, this is pity that I can't share this code
(and BTW that I can't benefit of other's one!)
I though the solution was to deliver my own (eric)misc library, you know...
But then we would rapidly be overcome by all miscmisc from world, and it
would be difficult to find specific functions with all that libraries.
To me, a possible solution would be to have a page on CRAN listing such R
files. Then, everyone would be able to upload R files with a short comment
(what does the functions do). I am thinking about something less
"strict"
than libraries: for that, no reason to test the code (programmer's
responsability). Then, maybe sometimes there would be enough pieces of code
on a statistical subject to justify the creation of a library (still with
the mind: a library is a collection of tools designed to help on a precise
situation).
While I'm at it, it would also be nice to have a shared page on
screenshots/graphics. For sure, I really enjoy to use R to produce
wonderfull graphics. Not only would it be nice sometimes to show them, but
it would also be the occasion to demonstrate R possibilities for newcomers
(think on color graphics including mathematics). R would never have enough
publicity!

Eric,
What you propose is similar (but not exactly the same) as electronic
reference cards we discussed earlier here and in R-SIG-GUI. A code
repository and a graph gallery,...humm, why not! It seems appealing to me.
Somebody has to take the initiative to start it. So,... go ahead!
Bonne journee,
Philippe

This comes up from time to time; at the moment I can't find the thread in the mailing list archives. The advantage, obviously, would be to make all this accumulated code available to the R community. The disadvantage would be that such a heap of code would be highly heterogeneous -- some stuff would work, some wouldn't, some would work originally but obsolesce -- and the good stuff would get lost anyway. On the other hand, you're right that it would be hard to find the functions one wanted in a set of "miscmisc" packages (but would it be any harder than finding it in a random heap of contributed code?) I guess I don't have a good answer; I would encourage you to bundle your stuff up into a little library, even if you don't think it's enough. (I am equally guilty of laziness: I've written a variety of packages for landscape generation, genetic stock analysis, 3D graphics, maximum likelihood ... but while I have put them up on my own web page at http://www.zoo.ufl.edu/bolker/R, I've never submitted them to CRAN for most of the reasons you cite.) http://lark.cc.ukans.edu/~pauljohn/R/statsRus.html is a good collection of (tiny) bits and pieces, but it depends on a single person for updating (and for keeping it coherent ...)
