I really liked this article on Notepad++ integration with R, I am a fan for anything like enhanced code editors and GUIs (and etc) which make R a more easier tool for the common man , and the little tech newbie.
Read it or glance through if you havent looked at the June version of R Journal, the article is on Page 62.
