Rscript.Ra(1) Scripting front-end to just-in-time compilation support for R


Rscript [--options] [-e expr] file [args]


A binary front-end to Ra, for use in scripting applications. Ra is functionally identical to R but provides just-in-time compilation of loops and arithmetic expressions in loops. This usually makes arithmetic in Ra much faster. Ra will also typically run a little faster than standard R even when just-in-time compilation is not enabled.

See the R documentation for more.
