```Hi

beside other options if you do not want to learn how to order factor
levels

Days <- c("Monday", "Tuesday", "Wed", "Thu", "Fri", "Sat","Sun")
Hum <-c(56,57,60,75,62,67,70)
Temp<-c(76,77,81,95,82,77,83)

> limits<-range(c(Hum, Temp))
> limits
[1] 56 95
> plot(1:7, Hum, ylim=limits)
> points(1:7, Temp, col=2)
> plot(1:7, Hum, ylim=limits, axes=F)
> points(1:7, Temp, col=2)
> axis(1, at=1:7, Days)
> axis(2)
> box()

this may work for you if you get rid of unnecessary matrix call.

Petr
