[R] xyplot - show values of a series on graph

[baptiste auguie]

with ggplot2,

d <- melt(df2,id="year")
qplot(year,value,data=d,colour=variable,geom=c("line","point")) +
geom_text(data= subset(d, variable == "cars"), aes(label=value))


with lattice, my best guess would be to use grid.text in a custom  
panel function.


Hope this helps,

baptiste
