R-devel object header changes that require reinstalling packages

luke-tierney
For anyone using the development version of R:

svn revision 73243 introduces some changes to the memory layout of R
objects that require reinstalling packages using compiled
code. Attempting to load incompatible packages should signal an
error. These changes are to support a new extension framework for
basic R objects
(https://svn.r-project.org/R/branches/ALTREP/ALTREP.html outlines the
framework).  Merging the remainder of the framework should not
introduce more binary changes and is expected to occur in the next few
months.

Best,

luke

Thank you for the nice writeup, hope this makes it into the R journal.
The spelling package finds a few typos:

> spelling::spell_check_files('ALTREP.md', lang = 'en_US')

  WORD              FOUND IN
abstrct           altrep.md:39
