A custom 'panel.groups' will let you condition on group number (see ?panel.superpose): xyplot(cars+trucks~year, data=df2, type="o", panel = panel.superpose, panel.groups = function(x, y, ..., group.number) { panel.xyplot(x,y,...) if (group.number == 1) { require(grid) grid.text(unit(x,"native"), unit(y,"native"), label=y, just="top") } }) -Deepayan > > > > 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.
