我試圖從R內使用下面的命令調用的Cygwin中調用的Cygwin：來自R
shell("cd C:\\cygwin\\bin & bash --login -i testfile2.txt", intern = T)
在Cygwin我試着用別的程序（教堂）。該invokation在testfile2.txt，看起來像這樣：
/cygdrive/c/cygwin/home/$USER/jschurch/bher /cygdrive/c/cygwin/home/$USER/foo.church > /cygdrive/c/cygwin/home/$USER/output.txt
不過，我得到以下錯誤消息：
> shell("@echo on & cd C:\\cygwin\\bin & bash --login -i testfile2.txt", intern = T)

任何人都可以解釋我，如何處理這個問題？
謝謝， 大衛
除非您的命令直接從cmd.exe會話中正確運行，否則這不是一個'R'問題，也不可能是一個'cygwin'問題。 –
