[R] setting xlim in plot of POSIXlt values

[Michael D. Sohn]

I'm plotting values against date:
theX <- paste(theval$Date, theval$Time)
theX <- strptime(theX, format="%m/%d/%Y %H:%M:%S")
plot(theX, theval$Value, type="l", ylim=c(0, 1500))

How do I set the xlimits?  I tried:

plot(theX, theval$Value, type="l", xlim=c(theX[1], theX[100]), ylim=c(0,
1500))

what am I missing?

thanks,
Mike
