No.  It doesn't get any harder either: the help that worked before still
works after the change.

I verified that the settings in my .emacs files are being read in; I
wasn't entirely sure where emacs thought home was under Windows.

The thing that starts doesn't look like a web browser, though it
probably is underneath.  It's the standard MS Windows help window, with
tabs for contents, index, and search.

I looked under the installation of R.
doc\html\search\index.txt has
Entry: setClass
Aliases: setClass
Keywords: programming classes methods
Description: Create a Class Definition
URL: ../../../library/methods/html/setClass.html

and that last file exists and the contents look fine.
