example on front page doesn't work in R 2.0.1

On http://www.r-project.org/, there is an R script linked to the top 
graphic, http://www.r-project.org/misc/acpclust.R. This script says it 
works in R 1.8.1, but in 2.0.1 it gives (me):

source("acpclust.R")

Loading required package: ade4
Loading required package: mva
Loading required package: RColorBrewer
Loading required package: pixmap
Loading required package: ade4
Error in plotacpclust(swiss[, 1:5], 1, 3, hcut = 48) :
        couldn't find function "s.corcircle"
In addition: Warning messages:
1: There is no package called 'ade4' in: library(package, character.only 
= TRUE, logical = TRUE, warn.conflicts = warn.conflicts,
2: package 'mva' has been merged into 'stats'
3: There is no package called 'RColorBrewer' in: library(package, 
character.only = TRUE, logical = TRUE, warn.conflicts = warn.conflicts,
4: There is no package called 'pixmap' in: library(package, 
character.only = TRUE, logical = TRUE, warn.conflicts = warn.conflicts,
5: There is no package called 'ade4' in: library(package, character.only 
= TRUE, logical = TRUE, warn.conflicts = warn.conflicts,

Maybe you want to adjust this! :)

Thank you very much very this very very useful program! It saved me from 
Excel/Gnumeric. ;)
