[R] lattice: how to add points to the plot generated by levelplot()?

[Walmes Zeviani]

You can use

levelplot(runif(100)~rep(1:10, each=10)+rep(1:10, times=10))
trellis.focus("panel", 1, 1, highlight=FALSE)
 lpoints(runif(100,0,10), runif(100,0,10), pch=2, col=2, cex=2)
trellis.unfocus()

# or

levelplot(runif(100)~rep(1:10, each=10)+rep(1:10, times=10),
          panel=function(...){
            panel.levelplot(...)
            grid.points(runif(100,0,10), runif(100,0,10), pch=2)
          }
          )
