Dear R experts:
I need to get this plot, but also with 95% confidence interval bands:
hour <- c(1, 2, 3, 4, 5, 6)
millivolts <- c(3.5, 5, 7.5, 13, 40, 58)
plot(hour, millivolts, xlim=c(1,10), ylim=c(0,1000))
pm <- lm(millivolts ~ poly(hour, 3))
curve(predict(pm, data.frame(hour=
Look at the "interval" option in ?predict.lm.
