SYNOPSIS

R [options] [< infile] [> outfile]
R CMD command [arguments]

DESCRIPTION

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.
