Wrapping R for windows in a com dll
...the
proxy dll ("Rproxy.dll"). Perhaps I don't really understand the reason for
going throug the proxy in the first place, but it seems like an unnecessary
indirection for an application which is not intended to use DCom. To this
end I have been trying to use the functions declared in rproxy_impl.h (I've
tried rtest.c as well, aka the readme file in the front-ends directory). It
is my understanding that these functions provide access to interface
functions contained in R.dll. However, there does not seem to be an R.exp or
R.lib file in the source code or R binary distribution.

creating custom I/O for R
Dear R developers,
I am building an ActiveX Com wrapper for R. I have successfully implemented
an Evaluate function using rproxy_impl.c and rtest.c as examples. The Com
object as it stands at the moment is similar to Thomas Baier's automation
server StatConnectorSrv.exe except that it does not use the Proxy. My goal
it to include a couple of activeX controls in the library: One to provide a
terminal-like interface to R and th...

error handling
Hello R developers,
Platform: Windows 2000.
Compiler: GNU GCC - 2.95.2 (CRTDLL)
I have a C function for evaluating commands using eval(SEXP,SEXP) which is
included in a personal make of R.dll. (Similiar to R_Proxy_evaluate() in
rproxy_impl.c) Using SETJMP to catch errors works but there is a problem.
For example, the following code:
if (SETJMP(R_ToplevelContext->cjmpbuf)) // R_ToplevelContext->cjmpbuf
R_GlobalContext->cjmpbuf
return FALSE;
R_CurrentExpr = eval(R_CurrentExpr , rho);
will appear to work the first time the...
