Hi Jorge --
I hesitate to suggest this unsupported solution (as these public
suggestions tend to mean that the solution disappears!), but in C
extern void R_SetErrorHook(void (*)(SEXP, char *));
void
my_ErrorHook(SEXP call, char *message)
{
/*
etc; e.g., cache message, perhaps reset error hook (hook is
removed after error; nested R-level try() may mean multiple
errors per R_tryEval?
*/
}
and then
...
R_SetErrorHook( my_ErrorHook );
PROTECT(value = R_tryEval( expr, env, errorOccurred ));
if( *errorOccurred ) {
/* etc, e.g., retrieve error message(s) from cache */
}
/*
hmm, maybe R_SetErrorHook needs to be cleared here, or at
least replaced with a no-op?
*/
...
This is an R-devel question, not R-help.
