r

NAME

r - Provides hash-bang (#!) capability for R (www.r-project.org)

SYNOPSIS

r [options] [-|file]

DESCRIPTION

Launches GNU R to execute the specified file containing R commands, or takes commands from stdin if '-' is used to denote stdin, using the specified options. This makes it suitable to create R scripts via the so-called shebang '#!/' line.

OPTIONS

-h, --help

Display a short help list.

--usage

Give a short usage message.

-V, --version

Show the version number.

-v, --vanilla

Pass the '--vanilla' option to R.

-p, --verbose

Print the value of expressions to the console.

-l, --packages list

Load the R packages from the comma-separated 'list'.

-e, --eval expr

Evaluate 'expr' in R.

USAGE

r can be used in command-line 'pipes' as well as in 'shebang'-style scripts.

NOTE

The executable program is called r, but the project is called littler to avoid confusion with the real GNU R.

SEE ALSO

The GNU R language is documented extensively at the R website (http://www.r-project.org) and in several manuals available in html, info and pdf.
