A bit off topic, but I think I can agree (even though I just used emacs for a week or two).
It's the same with R. I always complain to one of my colleagues (he is an R expert) that the 
help in R is crap. He says the R help is great, because it is written by experts for experts...

It states to find customization you type M-x customize-group ret ess. I access a file which invokes ess (a SAS source) and do this, which brings up the various customize dialogs. I looked for R, and find it as a dialect of S.
