*Rscript [#j81097ff]
WindowsOSコマンドライン実行用~
R2.5.0から使えるようになっている~
RCMD BATCHより柔軟~
Usage: /path/to/Rscript [--options] [-e expr] file [args]
--options accepted are
--help Print usage and exit
--version Print version and exit
--verbose Print information on progress
--default-packages=list
Where 'list' is a comma-separated set
of package names, or 'NULL'
or options to R, in addition to --slave --no-restore, such as
--save Do save workspace at the end of the session
--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 .Rprofile or ~/.Rprofile files
--restore Do restore previously saved objects at startup
--vanilla Combine --no-save, --no-restore, --no-site-file
--no-init-file and --no-environ

***バッチ実行(Rscript) [#jd16bc2c]
バッチ実行には、Rscript.exe を使うこともできます。~
Rscript [--options] [-e expr] inputfile [args]
Rscript には出力ファイルを指定するオプションがありませんが、出力のリダイレクトで代用できます。~
Windows 版の Rcmd BATCH ではスクリプトへ引数を渡す機能がうまく使えませんが、Rscript ではちゃんと引数を渡すことができます。~
Rscript は直接に表現式を書ける -e オプションが利用でき（このオプションは Rterm の機能）、かなり便利です。~
Rscript -e "commandArgs(); proc.time()" arg1 arg2 arg3
***リダイレクト [#ub0a4c48]
Rscript [--options] [-e expr] inputfile [args] > outputfile
inputfileがutf-8で作成されていると、outputfileもutf-8になる。~

NAME
R - a language for data analysis and graphics
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 defin-
ing new functions.
On platforms which support the dlopen(3) interface, Fortran and C code
can be linked and called at run time.
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-
cuted.
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
RHOME Print path to R home directory and exit
--save Do save data sets at the end of the session
--no-save
Don't save them
--no-environ
Don't read the site and user environment files
--no-site-file

--no-restore-data
Don't restore previously saved data sets
--no-restore-history
Don't restore the R history file
--no-restore

--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
--min-vsize=N
Set vector heap min to N bytes; '4M' = 4 MegaB
--max-vsize=N
Set vector heap max to N bytes;
--min-nsize=N
Set min number of cons cells to N
--max-nsize=N
Set max number of cons cells to N
-q, --quiet
Don't print startup message
--silent
Same as --quiet
--slave
Make R run as quietly as possible
--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, --gui=TYPE
Use TYPE as GUI; possible values are 'X11' (default), 'none' and
'gnome'
--args Skip the rest of the command line
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

- Apache などのWeb Service での利用例はないでしょうか？ -- [[Trix]] &new{2008-10-14 (火) 16:46:58};
- 以下のような form を作って，action を記述する a.cgi を用意してやる。当然，内容が固定されているのではおもしろくないので，input タグで引数をわたしたり，a.cgi 自体を動的に生成したり。やり方は色々。ただし，セキュリティーに注意。ヘタにやるととんでもないことになりかねませんからね。~
HTML ファイル
<html>
<head>
<title>ドライバー</title>
</head>
<body>
<form method="post" action="a.cgi">
<input type="submit" value="go">
<input type="reset" value="reset">
</form>
</body>
</html>
スクリプト（a.cgi）
#!/usr/local/bin/gawk -f
BEGIN {
out = "a.R"
print "cat('Content-type: text/html\n\n<html><head><title></title></head><body>')" > out
print "x <- rnorm(1000); mean(x)" > out
print "</body></html>" > out
close(out)
system("/usr/local/bin/R --vanilla --slave < a.R")
}
- ありがとうございます。参考にさせていただきます。 -- [[Trix]] &new{2008-10-15 (水) 00:13:38};
