search for: r_objecttable

We recently started noticing freezes that appear only on 32bit systems (both linux and windows) with a relatively recent versions of R 3.2.0, including the RC. It looks like the problem can be traced back to the use of R_ObjectTables (see R_ext/Callbacks.h) The problem is a bit difficult to reproduce because it does not appear on x64 and because the official R interface to this functionality, the RObjectTables package from OmegaHat, is no longer maintained. I created a slightly updated version of RObjectTables package (added...

Hello, Is it possible to have the effect of UserDefinedDatabase outside of "attached" environments ? Can I disguise an environment of the sys.frames() as a UserDefinedDatabase ? This seems to suggest that it might be possible : > f <- function(){ e <- environment(); class(e) <- "UserDefinedDatabase"; ff } > f() *** caught segfault *** address (nil),

...else. 2. I'm willing to maintain the central server and work on the infrastructure, but help will definitely be needed. Also, if there's significant interested, maybe R core would be interested in this. 3. What exactly is PopCon tracking as far as symbol names go? It currently used an R_ObjectTable object attached to the search path to capture names, but is this the best way? see http://www.omegahat.org/RObjectTables/. It's also replacing base::getHook to trap library loads. 4. What else would be interesting to track? Some folks have suggested various bits of R.Version() output. Her...
