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 wor...
