R help - Mar 2012 - show and produce PDF file with pdf() and dev.off( ) in function

Hi all,

I know how to use pdf() and dev.off() to produce and save a graph.

However, when I put them in a function say 

myplot(x=1:20){
  pdf("xplot.pdf")
  plot(x)
  dev.off()
}

the function work. But is there a way show the graph in R as well as saving
it to the workspace?

Thanks.

1) thats not a function (i'm sure just a mistake)
2) Just add another plot line 

myplot <- function(x){ 
  plot(x) 
  pdf("xplot.pdf") 
  plot(x) 
  dev.off() 
} 

myplot(1:20)

apart from the other answers, be aware that you have to 'print' the
graph with 

pl<-plot(x)
print(pl)

in case you're using lattice or ggplot2 plots.
