R help - Jul 2015 - change font size within the panel.text function (package lattice)

Dear all,
I am adding some text to the panels of a graph generated through the
lattice function using the argument:
   xyplot( ...,
              panel                function(x, y,...)
               {
                   panel.xyplot(x,y,...)
                   panel.text(0,0,labels=V[panel.number()])
               }

How can I regulate the font size of such text?

Best regards
luigi

library(lattice)
  A <- data.frame(x = rnorm(100), y = rnorm(100))
  xyplot(y ~ x, data = A,
  panel= function(x,y,...){panel.points(x,y,...)
                           panel.text(0.5, 0.2, "Hello, world",
cex=3)}
        )
