lattice has a type = "smooth" for this:
library(lattice)
xyplot(dist ~ speed, cars, type = c("smooth", "p"))
Or with a colored line:
xyplot(dist + dist ~ speed, cars, type = c("p", "smooth"), col =
1:2, distribute.type = TRUE)
In ggplot2 its also a one linear:
library(ggplot2)

Try this:
plot(x, y)
points(x, predict(fit), pch=16, col="blue")

Thanks a lot, it works.
Any ideas what's going on here?
y<-c(1.75, 1.41, 1.96, 1.03, 2.38, 2.19, 1.81, 1.91, 1.47, 2.25, 1.53,
2.79, 2.54, 2.36, 2.65,
2.69, 2.58, 3.27, 3.52, 2.93)
x<-c(0.59, 0.49, 0.65, 0.41, 0.84, 0.87, 0.69, 0.72, 0.67, 0.93, 0.76,
1.04, 0.87, 0.92, 0.92,
1.04, 0.94, 1.15, 1.1
Try this:
cars.lo <- loess(dist ~ speed, cars)
with(cars, plot(speed, dist))
lines(predict(cars.lo), col="blue")

Dear all,
To draw a lowess line on a plot was a piece of cake; to draw a loess
line, however, seems not that easy. Is the loess plotting implemented
at all in relation to the loess function, or do I have to look in
add-on packages?
Thanks,
Marcin
