问题
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?
回答1:
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')

Martin.
