...stop("bad handler specification") .Internal(.addCondHands(classes, handlers, parentenv, NULL, TRUE)) expr } <environment: namespace:base> but it does not work, probably because the handler stack is reset somewhere. Would it work if I poke into the RTopLevel.handlerstack instead of the R_HandlerStack as .addCondHands is doing ?

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 ? Romain -- Romain Francois Independent R Consultant +33(0) 6 28 91 30 30 http://romainfrancois.blog.free.fr
