Re: [R] how to run system command
Yes, not cygwin\bin but Rtools\bin (which is in my path:) Sys.which(date) date Z:\\R\\Rtools\\bin\\date.exe The OP's error message (Error in system(date, intern = TRUE) : 'date' not found) suggests he has no 'date' in his path. I see ?system says DOS internal commands, ... cannot be used: see shell, so you and others are correct in recommending 'shell' rather than 'system'. Sorry for the noise :-( At least I've learned something :-) Best regards, KJ William Dunlap wdun...@tibco.com wrote in message news:e66794e69cfde04d9a70842786030b93283...@pa-mbx04.na.tibco.com...

Re: [R] how to run system command
Those are error messages from the shell, not real values for what you think you are doing. Are you looking for the getwd() and Sys.date() functions instead?

You can't use system() to run system commands that don't exist on your system. I don't run windows, and have no idea what the command/syntax to obtain the date might be. It was already suggested you use Sys.Date() instead, and only use system() for system commands not duplicated in R.
