       R - a language for data analysis	and graphics

       R [options] [_ infile] [_ outfile]
       R CMD command [arguments]

       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 de-
       veloped	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	defin-
       ing 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-exe-

       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

	      Print version info and exit

	      Specify encoding to be used for stdin

       --encoding ENC

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

	      Don't save it

	      and --no-environ

	      Don't use	readline for command-line editing

	      Set max size of protect stack to N

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

	      Set vector heap minimum to N bytes; '4M' = 4 MegaB

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

	      Same as --quiet

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