# Ra(1)

Just-in-time compilation support for R

## NAME

Ra - Just-in-time compilation support for R

## 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.

## SEE ALSO

The documentation for *R*, and the website at *http://www.milbo.users.sonic.net/ra/index.html*.
