I was thinking that the RObjectTables appeared before the active binding stuff was introduced. On quick examination, it seems the active binding mechanism might be a more stable way to go. That's how it was done in filehash. -roger On Tue, Jul 24, 2012 at 9:15 AM, wrote: > In my original reply

Maybe it is worth considering to document this functionality a bit more, or expose some wrappers in R? It's a bit obscure right now, which seems both dangerous in terms of maintenance and a missed opportunity (especially if people are already building on it). On Tue, Jul 24, 2012 at 2:06 AM, M

Luke, Please keep me advised on this, because the Qt interfaces heavily rely on the ObjectTables (btw, it has worked great for my use cases). Michael On Fri, Jul 20, 2012 at 7:32 AM, wrote: > I believe everyone who has worked on the relevant files has tried to > maintain this functionality, bu

I was wondering if anyone knows more about the state of RObjectTables. This largely undocumented functionality was introduced by Duncan around 2002 somewhere and enables you create an environment where the contents are dynamically queried by R through a hook function. It is mentioned in R Internals
