Good Day All,

I want to add text floating in my wireframe plot and I am rather confused. I can certainly add the text as a title (e.g. main="Hello World") but I would rather not have my particular text in the title

Here is a sample wireframe:

```
  library(lattice)
  #set up some simplified data
  x <- seq(-.8, .8, .1)
  y <- seq(-.8, .8, .1)
  myGrid <- data.frame(expand.grid(x,y))
  colnames(myGrid) <- c("x","y")
  myGrid$z <- myGrid$x + myGrid$y

  wireframe(
     myGrid$z ~ myGrid$x * myGrid$y, 
     xlab="X", ylab="Y", zlab="Z",
     scales = list(z.ticks=5, arrows=FALSE, col="black", font=3, tck=1)
  )

```

If I wanted to add "Hello World" in this plot floating somewhere how would I do that ?
