Thank you very much for your help. I tried to use lattice but I'm not sure how to restrict it to display only the values of "cars".
xyplot(cars+trucks~year, data=df2, type="o", panel=function(x,y,...){ panel.xyplot(x,y,...) grid.text(unit(x,"native"),unit(y,"native"),label=y, just="top")} ) baptiste auguie-2 wrote: > > 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 > > On 8 Apr 2009, at 19:40, taz9 wrote: > >> >> Hi All, >> >> I have a very simple graph: >> >> cars <- c(1, 3, 6, 4, 9) >> trucks <- c(2, 5, 4, 5, 12) >> year <- c(2004, 2005, 2006, 2007, 2008) >> df2<-data.frame(cars,trucks,year) >> xyplot(cars+trucks~year, data=df2, type="o") >> >> I need to show the values of "cars" on the graph.
