The resulting binaries will contain both native code and LLVM bitcode.\n<p>Pre-installed packages are also built in this manner.<br \/>\n FastR loads and runs native extension code by default, but when run with the option '\u2014R.BackEnd=llvm', it will use bitcode. The LLVM backend can be selectively used for certain R packages by specifying '\u2014R.BackEndLLVM=pkg1,pkg2'. In case of issues during package installation, you can revert everything back by calling fastr.setToolchain('native') or manually editing the $FASTR_HOME\/etc\/Makeconf file;<\/p>\n<li class=\"l\"> In
