[R] R - API ?

[Yoon, Hoon (CICG - NY Program Trading)]

Hi,

   I thought that this was very close to what I was asking before. So, I
just pulled some info together for everyone's benefit, especially the stuff
Guido mentioned. I hope that people who are interested will keep each other
updated.
  Thanks,

The source to Guido's windows version is on CRAN, cunningly hidden
under "Binaries" in the 
 bin/ms-windows/win-32-devel/ directory. 

The sockets package is not on CRAN, since it will reasonably soon be
part of the R distribution (certainly R0.64, possibly a R0.63.x). It is
at
  http://www.biostat.washington.edu/~thomas/sockets.tgz

  Jeff Banfield of my department has build a front-end for R which gives
output to a browser.  I believe he uses Perl and we do run it on Solaris.

Hi,

I'm also very much interested in linking VB to R, perhaps also running R on
a different computer on the network (like for example MathSoft's
StatServer).
Unfortunately, my current high-priority software development projects make
that this can not be a short-term occupation, but rather a medium-to-long
term project. However, I would be glad to hear from you about the progress
you were able to make in your project, although I can't offer any help, at
least for the time being.

Thank you very much in advance,

Zivan
