"R
[http://www.r-project.org]
is a language and environment for statistical computing and
graphics" [http://www.r-project.org/about.html].  For more background on R,
see the July 2003 installment of "Server Clinic" [http://phaseit.net/claird/comp.os.linux.development.system/ServerClinic.html],
as well as the later series here
[http://www-128.ibm.com/developerworks/linux/library/l-r1/]
and here
[http://www-128.ibm.com/developerworks/linux/library/l-r2].

R apparently binds to [Tcl], [Tk], and [Visual Tcl]
in ways that have yet to be clearly described
[http://www.r-project.org/nocvs/mail/r-announce/1999/0023.html].
Seductive screen-shots appear at http://www.bioconductor.org/Screenshots/index.html , for example.
[Brodgar] is crucial.

[Peter Dalgaard] says in comp.lang.tcl that
http://CRAN.R-project.org/doc/Rnews/
should be used as a source for more recent information;
particularly in vol 1/3 and 2/3.

He goes on to say:


"What we currently have is a Tcl interpreter embedded in R and
interface routines and (some) object reflection and communication
mechanisms, which allow you to run Tcl stuff from within R.

What we don't have is the reverse: Mechanisms that let you control R
from Tcl. Well, we do have some rudiments of it, but not as elaborate
as in the other direction. In principle R is embeddable; you can build
R as a shared object and link it into another program, but you
probably need to jump through a few hoops to get event loops and such
stuff right. (I believe http://developer.r-project.org/embedded.html
is the best documentation we have.)"

That was the situation in early 2003.  A few hours before the year ended,
though, [Neil McKay] announced availability of [Rtcl].

 Description: Statistical computing and visualization language,
        similar to the S language.
        Provides a wide variety of techniques.
        Comes with a tcltk package, providing interface and language bindings
         for Tcl/Tk.
        Makes use of plplot.
        Note that Mark Myatt mailto:mark@myatt.demon.co.uk is
         writing a syntax highlighting editor to be used as a front-end
         of R; contact him for details.
        Currently at version 1.5.0 .
