Running System Commands |
You can ask the operating system to perform a command with the
system command:
> system("sleep 10") # Run OS command sleep with argument 10
> system("sleep 10", wait=FALSE) # Run OS command but don't wait (MS/Windows)
> system("sleep 10 &") # Run OS command but don't wait (GNU/Linux)
> l <- system("ls", intern=TRUE) # Run OS command and collect output
