I'm not sure what you were trying to do, because:
1) You didn't provide a reproducible example (I don't have 'crude.csv'), and
2) it doesn't make sense to use unnamed arguments for the first two
arguments, and then use a named argument to re-specify the second
argument (order.by).

You probably wanted something like:
close <- xts(x[,2], as.Date(x[,1], format='%d-%b-%y'))
