[R] retrieve from function

[threshold]

Hi, say I got the function:
> x=function(nbr){y<-rnorm(nbr);y1 <- mean(y);plot(y)}

how can I retrieve value of y1, when I need it. 

I don't want:
> x=function(nbr){y<-rnorm(nbr);y1 <<- mean(y);plot(y)}
> y1

I want someting like:
"x$y1" and then I get the value

Many thanks, robert
