I assume this is somehow related to changes in R 3.5.0 (maybe related to this <https://github.com/wch/r-source/commit/0ba66a2bc236ae5b009af910688575aa4adddd2c>?), but I'm not sure how to debug it (as I don't have this environment set-up), not am I sure what is actually c...

Hi, I am experiencing a warning message when I load a large R object created in an R 3.6 session in R 3.5.* , as follows: ``` Warning message: In load(?GDSCv2.RData?) : cannot unserialize ALTVEC object of class ?wrap_logical? from package ?base?; returning length zero vector ``` Of relevant information may be that the large R object (a data structure defined in my Bioconductor package PharmacoGx), was in part created including data frames which were cast from data.tables. I noticed that th...

...re info on the problem if you manually build a connection between two R processes and export the ALTREP object. See output below ``` > con <- socketConnection(port = 1234,server = FALSE) > gctorture() > x <- unserialize(con) Warning message: In unserialize(con) : cannot unserialize ALTVEC object of class 'mmap_real' from package 'simplemmap'; returning length zero vector ``` It seems like simplemmap did not get loaded correctly on the worker. If you run `library( simplemmap)` before unserializing the ALTREP, there will be no problem. But I suppose we should be able...

...The default methods in altrep.c should do the right think. A reasonable name for the abstract class would be 'altlist'. 'altrep' methods that a class can provide: Unserialize or UnserializeEX Serialized_state Duplicate or DuplicateEx Coerce Inspect Length 'altvec' methods a class should provide: Extract_subset not Dataptr not Dataptr_or_null 'altlist' specific methods: Elt Set_elt Best, luke On Tue, 23 Jul 2019, Gabriel Becker wrote: > Hi Kylie, > > Is it a list with only numerics in it?

Hi All, I've finished the first draft of the 2.8 release notes: http://llvm.org/docs/ReleaseNotes.html Please feel free to commit improvements and enhancements. There are "a lot" of changes that went into 2.8, but I think I've scraped most of them out of the commits. However, it is also highly likely that I missed something, so if I missed your favorite feature, please speak

Hi Kylie, Is it a list with only numerics in it? (I only see REALSXPs there, but obviously inspect isn't showing all of them). If so, you could load it up into one big vector and then also keep partitioning information around. Bioconductor does this (see ?IRanges::CompressedList ). The potential benefit here being that the underlying large vector could then be a big out-of-memory altrep. How
