2 years ago Well. It looks like STDVEC_LENGTH is also not available. I may look into fixing this.

This package was broken by the removal of undocumented API headers in the R distribution. Sadly this greatly diminishes the value of rgo since the performance of the documented approach requiring interchange via Cgo is significantly worse than the direct memory access that this package provided. It also great reduces the flexibility of operations that could be performed using rgo.
The change that breaks this is git-svn-id: https://svn.r-project.org/R/trunk@80644 00db46b3-68df-0310-9c12-caf00c1e9a41.
