Title: ALTREP: Alternate Representations of Basic R Objects

Abstract: The ALTREP provide framework provides infrastructure to support for alternate representations of basic R objects. Some examples include R vectors with data in memory-mapped files, compact representation of arithmetic sequences, deferred computations, and adding meta-data to objects. This talk will outline the framework, present some examples of its use, and describe the current state of incorporating the framework into the R distribution.
