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, 1.13, 1.09)

plot(x,y,xlim=c(0.4,2.5))
fit<-loess(y~x)
lines(predict(fit), col="blue")
