libRmath.js

Javascript ( TypeScript ) Pure Implementation of Statistical R "core" numerical libRmath.so library found here https://svn.r-project.org/R/trunk/src/nmath/

Progress (DONE and TODO)

Work in progress (see list below of all c modules that need to be ported), please considering helping out and bring R core functionality to Javascript.

I first list the modules DONE so far, lets start at a positive note)
