Jun,
The par() command is to give extra margin on right side to accomodate the y
axis label.
I recognize, like Rolf, that three y axis can be cumbersome, confuse. So, I
would adopt another approach using lattice::xyplot()
require(reshape)
x <- melt(x, id="Time")
str(x)
require(lattice)
xyplot(value~Time|variable, data=x, layout=c(3,1),
type="l", scales=list(y=list(relation="free")))
