```Actually, it's a bit more complex than just plot(). First you have to
make Days an ordered factor, otherwise you get indeed that error.

days <- c("Mon", "Tue", "Wed", "Thu", "Fri", "Sat","Sun")
Days <- factor(days,levels=days,ordered=T)

Then you want to make a plot with 2 axes, you should check :

and reconsider...

Kind regards
