R - a language for data analysis and graphics

NAME

SYNOPSIS

R [ options] [< infile] [> outfile]

R CMD command [arguments]

DESCRIPTION

Start R, a system for statistical computation and graphics, with the specified options, or invoke an R tool via the 'R CMD' interface.

R is a language which bears a passing resemblance to the S language developed at AT&T Bell Laboratories. It provides support for a variety of statistical and graphical analyses. R is a true computer language which contains a number of control-flow constructions for iteration and alternation. It allows users to add additional functionality by defining new functions.

On systems which have the GNU readline(3) library, R will maintain a command history, so that commands can be recalled, edited and re-executed.

OPTIONS

Most options control what happens at the beginning and at the end of an R session, in particular which files are being read and written, and how much memory is reserved for the R process.

-h, --help: Print short help message and exit

--version: Print version info and exit

--encoding=ENC: Specify encoding to be used for stdin

--encoding ENC

RHOME: Print path to R home directory and exit

--save: Do save workspace at the end of the session

--no-save: Don't save it

--no-environ: Don't read the site and user environment files

--no-site-file: Don't read the site-wide Rprofile

--no-init-file: Don't read the user R profile

--restore: Do restore previously saved objects at startup

--no-restore-data: Don't restore previously saved objects

--no-restore-history: Don't restore the R history file

--no-restore: Don't restore anything

--vanilla: Combine --no-save, --no-restore, --no-site-file, --no-init-file and --no-environ

--no-readline: Don't use readline for command-line editing

--max-ppsize=N: Set max size of protect stack to N

--min-nsize=N: Set min number of fixed size obj's ("cons cells") to N

--min-vsize=N: Set vector heap minimum to N bytes; '4M' = 4 MegaB

-q, --quiet: Don't print startup message

--silent: Same as --quiet

-s, --no-echo: Make R run as quietly as possible

--interactive: Force an interactive session

--verbose: Print more information about progress

-d, --debugger=NAME: Run R through debugger NAME

--debugger-args=ARGS: Pass ARGS as arguments to the debugger

-g TYPE, --gui=TYPE: Use TYPE as GUI; possible values are 'X11' (default) and 'Tk'.

--arch=NAME: Specify a sub-architecture

--args: Skip the rest of the command line

-f FILE, --file=FILE: Take input from 'FILE'

-e EXPR: Execute 'EXPR' and exit

FILE may contain spaces but not shell metacharacters.

Commands:

BATCH: Run R in batch mode

COMPILE: Compile files for use with R

SHLIB: Build shared library for dynamic loading

INSTALL: Install add-on packages

REMOVE: Remove add-on packages

build: Build add-on packages

check: Check add-on packages

LINK: Front-end for creating executable programs

Rprof: Post-process R profiling files

Rdconv: Convert Rd format to various other formats
