R help - Jul 2016 - how to stop interpretation in system()

Hi,

I am trying to use system() to run some command in OS. such as

system("cmd 'a\tb')

however,  it alway runs
cmd 'a    b'
instead of
cmd 'a\tb'

How can I prevent system to interpret 'a\tb' to 'a    b'?


Thanks

You could escape the backslash.

system("cmd 'a\\tb'")

Yes. I forgot to  escape the escape. Thank you so much.
