...do is to dynamically load a shared library, and pass the name of a symbol as a string to my ode solver interface. The C wrapper would then retrieve the pointer to the function named by the string (or fail gracefully trying), and pass that pointer to LSODA. It looks like all I have to do is invoke R_FindSymbol with the name I am looking for as the first argument, and the null string as the second; the return value will be the pointer I am looking for. Am I right, or is it more complicated than that? R. Woodrow Setzer, Jr. Phone: (919) 541-0128 Biostat...

Dear all, I have some difficulty getting R-1.3.0 to run on the alpha, with osf4.0e (Tru64, or whatever they call it... :-) ). configure reports the following configuration: R is now configured for alphaev6-dec-osf4.0e Source directory: .

...veNativeRoutine in "src/main/dotcode.c". Specifically, the newer code adds this: errorcall(call, "\"%s\" not resolved from current namespace (%s)", buf, ns); And removes these lines: /* need to continue if the namespace search failed */ *fun = R_FindSymbol(buf, dll.DLLname, symbol); if (*fun) return args; Is that extra call to R_FindSymbol really all that's necessary to invoke the old "keep searching" behavior? Would it be a good idea to provide an optional way of finding a native routine regardless of where it's located, perha...

...en pass it down to the compiled code to use in the ode solver directly. Since getSymbolInfo() (new in 1.4.0) returns a pointer to the requested loaded function, it would seem to be part of the answer to my problem (when I asked this question some time ago, I was warned away from using the internal R_FindSymbol() (declared in Rdynload.h) as being potentially unstable). However, I cannot figure out how to pass the pointer through .Call or .External. Is this possible, or should I pass a string through to the compiled code, and find the pointer on that side (and how to do that)? Thanks. R. Woodrow Setze...

Hi everyone, I'm thinking about breaking up a large package I have to avoid loading some of the more specialised parts when it isn't necessary. The package is dependent on shared libraries. The base one will keep all of the core stuff like constructors etc and the specialised parts will need to access these. It is obviously possible to set the "local" flag to false, however

...libraries. I've configured the build appropriately but from what I can tell it's not currently supported: there are compile errors here and there and the mechanism for looking up base symbols (CFunTab in Rdynload.c??) seems to have been ripped out. I'm going to add enough code so that R_FindSymbol will at least return correct pointers for the base library (error: C symbol name "R_isMethodsDispatchOn" not in DLL for package "base"), but I was wondering whether if anyone else is working on this, or if this is scheduled to be phased out altogether. Thanks for the info, Al...

Dear R people We have two packages, where the first package (geoR) is required by the second (geoRglmm). Both packages have functions calling C-code via .C(). We would like to call C-functions included in the first package from within the C-code in the second package. Is this possible? An appropriate header file was included in the src directory of the second package but this alone did not
