R help - Sep 2008 - Installing DSE package.

Hello R users,

 I am trying to get package 'dse' and it seems to download OK: 
 
  bundle 'dse' successfully unpacked and MD5 sums checked 
 
  But when I try to use it I get: 
 
 > help(package="dse") 
 Error in .find.package(pkgName, lib.loc, verbose = verbose) : 
   there is no package called 'dse' 
 > library(dse) 
 Error in library(dse) : there is no package called 'dse' 
 
 
What is it that I am doing wrong? 
 
Thank you. 
 
 Kevin
