You cannot. I am a little involved in this multi-year process of bringing
mlpack to R: we had RcppMLPACK based on mlpack 1.*, but subsequent mlpack
releases required Boost serialization via linking which made packaging for R
challenging / impossible.
Thanks to amazing work of one GSoC student (and mlpack contributor) R is now
a properly exported language (among a few other) with auto-generated
bindings. And the CRAN source package is self-contained with all it needs
from mlpack. But the build is expensive as every mlpack algoriithm gets built
using these autogenerated binding so it simply takes a moment.
