无法从R调用cygwin命令 [英] Can't call cygwin commands from R
问题描述
我在windows框中工作,并使用cygwin模仿unix shell。还有我有R,并想从它运行任何系统命令。我相信 system('command')
会这样做,但它不适用于每个'命令
。例如 system('ls')
返回 / cygdrive / c / cygwin / bin / ls:写错误:错误的文件描述符
我认为这是由于R调用 ls>& -
,它也返回相同的错误。那么如何解决这个问题呢?
我希望你仍然对解决方案感兴趣。这里是我有:
- 从Windows启动R并通过路径调用cygwin可执行:
/cygwin/bin/ls.exe');
- 从cygwin内启动R:
- 开始cygwin
- 设置路径:
export PATH =$ PATH:/cygdrive/c/Programme/R-2.9.2/bin
- 调用R:
Rgui.exe
- 调用shell:
系统('ls')

I'm working in windows box, and using cygwin to imitate unix shell. Also I have R and want to run any system comand from it. I believe that system('command')
would do this, but it didn't work for each 'command'
. For example system('ls')
returns /cygdrive/c/cygwin/bin/ls: write error: Bad file descriptor
and I think that this is beacause R calls ls >& -
which also returns same error. So how solve this problem?
I hope you are still interested in a solution. Here is what I have:
- Start R from Windows and call cygwin executable by path:
system('C:/cygwin/bin/ls.exe');
- Start R from within cygwin:
- Start cygwin
- Set path:
export PATH="$PATH:/cygdrive/c/Programme/R-2.9.2/bin"
- Call R:
Rgui.exe
- Call shell:
system('ls')
