Size of R user base
I have been trying to determine the size of the R user base, and was
asked to share my findings with this mailing list. Although I still
don't have any definite estimate of this number, I do have some
interesting and indicative information:
1. It appears that there are about 100,000 S-PLUS users.
Rationale: According to Insightful's 2002 Annual Report, over 100,000

[OT] "Dispersion" in French
Greetings,
I'm posting this OT query here because of out very international
membership!
In the French sentence
"Les taux de tirage sont calcul??s de mani??re ?? ce que la
dispersion soit inf??rieure ?? 5 % dans chaque strate."
it would seem intended that the "dispersion" is to be calculated
in a specific way (unstated) -- otherwise, how to ensure that it

Missing data and Imputation
Hi Folks,
I'm currently looking at missing data/imputation
methods (including multiple imputation).
S-Plus has a "missing data library".
What similar resources are available within R?
Or does one roll one's own?
Best wishes to all,
Ted.

good editor for R sources ?
Dear all,
(Sorry if the question has already been answered.)
Could someone please suggest a good text editor for
writing R sources ?
(I know emacs exists ... but I find it a bit heavy).
I use crimson (http://www.crimsoneditor.com) which is
small and simple, but the R syntax seems not to be supported.
Thanks for any advice

Shafer's MI software for S-plus
Greetings folks,
Shafer's S-plus package "norm" for multiple imputation of
missing values in multivariate normal data has been most
kindly and usefully ported to R by Alvaro A. Novo.
Shafer's website
http://www.stat.psu.edu/~jls/
lists four S-plus packages in all:
NORM - multiple imputation of multivariate continuous data
CAT - multiple imputation of multivariate

clogit and general conditional logistic regression
Can someone clarify what I cannot make out from the
documentation?
The function 'clogit' in the 'survival' package is
described as performing a "conditional logistic regression".
Its return value is stated to be "an object of class clogit
which is a wrapper for a coxph object."
This suggests that its usefulness is confined to the sort of
data which arise in

win.metafile and Linux
Hi Folks,
I see that people have been discussing the win.metafile device
on the list since before 2000.
Yet I have never seen this on a Linux distribution of R.
Is this because the device works by making calls (GPL calls of
course!) to a proprietary Windows library?
In that case I can understand that it would be far from kosher to
implement it on Linux. But I'd like confirmation.

R GUI considerations (was: R, Wine, and multi-threadedness)
Hello,
Following a discussion initiated on r-devel, that mentions SciViews-R
and other GUIs issues for R, I would like to make comments (and would be
happy if these comments would initiate interesting initiatives).
A big, big problem with SciViews-R is that a part of it is written in
Visual Basic 6, a M$$$$ language, not supported any more, buggy, non
transposable to other platforms, etc,

replacing values in a vector
Hi all,
there is a vector v with several NAs. I want to create a new vector n of
the same length as v and the same NAs as in v and tried this:
n <- vector(length=length(v), mode="numeric")
replace(n, which(is.na(v)), NA)
but this does't work, all values in n are 0. What went wrong?
Thanks, Sven

Creating GUIs for R
Hi all,
I have looked around for help on creating GUIs for R, but haven't found
anything. I would be interested in any advice or webpages that have
information on the best language, tutorials etc. for creating simple GUIs.
Mainly I want to do this as a heuristic exercise.
Thanks for any help.

FW: R Reference Card and other help (especially useful for Newbies)
Hi all:
Newbies (and others!) may find useful the R Reference Card made available by
Tom Short of EPRI Solutions at http://www.rpad.org/Rpad/Rpad-refcard.pdf or
through
the "Contributed" link on CRAN (where some other reference cards are also
linked). It categorizes and organizes a bunch of R's basic, most used
functions so that they can be easily found. For example,

Converting S-Plus Libraries to R
Dear all!
I'd like to do multiple imputation of missing values with s-plus libraries
that are provided by Shafer (http://www.stat.psu.edu/~jls/misoftwa.html). I
wonder, whether these libraries are compatible or somehow convertible to R
(because I don't have S-plus), so that I can use this functions using the R
Program.
I would be happy if you could tell me,

SciViews-R_0.8-9 Console problem
Dear R users,
I successfully installed SciViews the other day. However, when I try to
run it now, the command/script window does not appear. Strange. Well,
actually I see a tendency to a script window (in the lower part of the
sciview window where it is suppose to be) during start up, but when the
program is entirely open, the script window is gone.

Mes programmes fonctionnent tr?s bien, mais SciViews me propose uniquement de les enregistrer au format txt sous un type de fichier "bloc notes".
