从R内部调用Cygwin

Question

我试图用下面的命令从R内部调用Cygwin：

shell("cd C:\\cygwin\\bin & bash --login -i testfile2.txt", intern = T)

在Cygwin中，我尝试调用另一个程序(教堂)。调用位于testfile2.txt中，如下所示：

/cygdrive/c/cygwin/home/$USER/jschurch/bher /cygdrive/c/cygwin/home/$USER/foo.church > /cygdrive/c/cygwin/home/$USER/output.txt

但是，我得到以下错误消息：

> shell("@echo on & cd C:\\cygwin\\bin & bash --login -i testfile2.txt", intern = T)

谁能给我解释一下，如何处理这个问题？

Answer 1

使用命令c:\cygwin\bin\run.exe从windows启动cygwin进程。它应该会解决这个问题。

run [ -p path ] command [ -wait ] arguments

使用-p path，您可以将路径添加到path环境变量。
