Please start R and enter the following commands:

library(splancs)
area = 6*4
lambda = 1.5
N = rpois(1,lambda*area)
u = runif(N,-2,4)
v = runif(N,0,4)
h = chull(u,v)
h = c(h,h[1])
plot(u[h],v[h],"l",asp=1)
points(u,v)

If you do not get the plot you're expecting, then
repost
  1) adding an informative subject line
  2) showing us what you tried without including
     your typos and other errors.

I think you'll find this a more effective strategy than
trying to replace core elements of R that you don't
understand with empty functions.
