Subject: [Rd] calling handlers within R_tryEval
Message-ID: <4A375074.2010401@dbmail.com>


Hello,

When using R_tryEval (from JRI in my case), is there a way to setup 
error recovery strategy and more generally calling handlers.
 From my reading of context.c, R_tryEval calls R_ToplevelExec which 
creates a context like this:

    begincontext(&thiscontext, CTXT_TOPLEVEL, R_NilValue, R_GlobalEnv,
         R_BaseEnv, R_NilValue, R_NilValue);

so I guess what I am trying to do is add "cend" and/or "handlerstack" to 
this context. Is this possible ? Are there examples of packages doing this ?
