This is very easy to do with ggplot:


p <- ggplot(temp, . ~ LocCode, aes=list(y=Density, x=Year)) (p <- ggpoint(p))
ggsmooth(p, method=lm, formula=y~poly(x,3))

You can also do it with fitted values in another column.

temp$fitted <- fitted(paraslm1)

p <- ggplot(temp, . ~ LocCode, aes=list(y=Density, x=Year)) (p <- ggpoint(p))
ggline(p, aes=list(y=fitted))
