...rlier versions, and is not guaranteed to remain unchanged.) o The header R_ext/Mathlib.h has been removed. It was replaced by Rmath.h in R 1.2.0. o PREXPR has been replaced by two macros, PREXPR for obtaining the expression and PRCODE for obtaining the code for use in eval. The macro BODY_EXPR has been added for use with closures. For a closure with a byte compiled body, the macro BODY_EXPR returns the expression that was compiled; if the body is not compiled then the body is returned. This is to support byte compilation. o Internal support for executing byte compiled code has...
