On RObjectTables
I believe everyone who has worked on the relevant files has tried to maintain this functionality, but as it seems to get used and tested very little I can't be sure it is functional at this point. The facility in its current form does complicate the internal code and limit some experiments we might otherwise do, so I would not be surprised if it was at least substantially changed in the next year or two.

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 and ?attach. This functionality is quite powerful and allows you to e.g. offload a big database of R objects to disk, yet use them as if they were in your workspace. The recent RProtoBuf package also uses some of this functionality to dynamically lookup proto definitions. I would like to do something similar, but I am not sure if support for this functionality will be or has been discontinued. The RObjectTables package is no longer available on OmegaHat and nothing has not been mentioned on the mailing lists for about 5 years. I found an old version of the package no github which seems to work, but as far as I understand, the package still needs the hooks from within R to work. So if this functionality is actually unsupported and might be removed at some point, I should probably not invest in it. [[alternative HTML version deleted]]
