R help - Oct 2005 - square and points on the same figure

Hi,
I have the following code to 
randomly generate the 
points:
csr <-function(n=60){
x=runif(n)
y=runif(n)
f=cbind(x,y)
}
plot(csr())

I wonder how to code to draw a square centering on 0.5,0.5; with the length of
each side to be 0.3 on the same figure with these plotted points?

Thanks,
Sam

?symbols

symbols(x=0.5, y=0.5, squares=c(0.3), add=TRUE)
