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')

    Regards,

    Martin.
