Please read the help for system, paying particular attention to the
intern argument.
> e <- system("date", intern=TRUE)
> e
[1] "Tue Mar  6 08:33:48 EST 2012"

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?
