Yes, you need that hook to get eldoc working in *R* buffers.

that is odd.  When you are in the file.R buffer, and that has a *R*
process associated with it, put your point over a function, such as
"rnorm" and then do 

  M-: (ess-eldoc)

if ess-eldoc is working, you should see the following in the minibuffer:

"rnorm: n, mean = 0, sd = 1"
