For example, plotting 20 pairs of $N(0,1)$ random variates can be
looked at via the two following chunks.

<<Plotting 20 N(0,1) RVs in XLispStat>>=
;; -*- mode: xlispstat -*-
(def test (normal-rand 20))
(def test2 (normal-rand 20))
(plot test test2)
@ 

The below code demonstrates that there isn't much difference between
Lisp and the S language (as implemented through the dialect, R).

<<Plotting 20 N(0,1) RVs in R>>=
## -*- mode: R -*-
test <- rnorm(20)
test2 <- rnorm(20)
plot(test,test2)
@ 

Finally, we could show how to do this in Stata or SAS, as follows:

<<Plotting 20 N(0,1) RVs in R>>=
gen test = normal(20)
gen test2 = normal(20)
plot test,test2
@
