[英]Run .bat file using shell() in R
I'm using the console of PDFSam to split and merge some PDF files. 我正在使用PDFSam的控制台来拆分和合并一些PDF文件。 I can do this semi-automatically using .bat files, but I would like to do the whole thing in R. 我可以使用.bat文件半自动执行此操作,但我想在R中完成所有操作。
This code in my .bat file works: 我的.bat文件中的此代码有效:
C:
cd "/Program Files/pdfsam/bin/"
run-console.bat -f "d:/delete/A_9.pdf" -o d:/delete -s BURST -overwrite split
But this "equivalent" code in my R shell command returns no errors, but doesn't seem to work. 但是我的R shell命令中的这个“等效”代码没有返回错误,但似乎不起作用。
shell('C:
cd "/Program Files/pdfsam/bin/"
run-console.bat -f "d:/delete/A_9.pdf" -o d:/delete -s BURST -overwrite split')
Is there an option I'm missing in my shell command? 我的shell命令中是否有一个选项? I've tried a few of the options listed in ?shell to no avail. 我已经尝试了一些在shell中列出的选项无济于事。
I'm using windows XP and R version 2.13.1 (2011-07-08) Platform: i386-pc-mingw32/i386 (32-bit) 我正在使用Windows XP和R版本2.13.1(2011-07-08)平台:i386-pc-mingw32 / i386(32位)
Thanks, Tom 谢谢,汤姆
You could pass multiple commands to shell by concatenating them by &
, so below should work: 你可以通过多个命令将通过连接它们外壳&
,所以下面应该工作:
shell('C: & cd C:/Program Files/pdfsam/bin & run-console.bat -f "d:/delete/A_9.pdf" -o d:/delete -s BURST -overwrite split')
But as a workaround you could temporary change R working directory: 但作为一种解决方法,您可以临时更改R工作目录:
current.wd <- getwd()
setwd("C:/Program Files/pdfsam/bin")
shell('run-console.bat -f "d:/delete/A_9.pdf" -o d:/delete -s BURST -overwrite split')
setwd(current.wd)
If you do it frequent write a function: 如果你经常写一个函数:
shell.in.dir <- function(dir, ...) {
current.wd <- getwd()
on.exit(setwd(current.wd))
setwd(dir)
shell(...)
}
shell.in.dir("C:/Program Files/pdfsam/bin",
'run-console.bat -f "d:/delete/A_9.pdf" -o d:/delete -s BURST -overwrite split')
这不是您问题的答案,但您可以尝试使用system("youBatFile.bat")
作为替代方案。
