[R] Help with Help on Windows

[Ross Boylan]

R 2.15.2 installed as a regular user on Windows 7.

Three issues:

1. There is a start menu item for "R 2.15.2 Help" that opens a local web 
page.  If I click on packages, then base, then abbreviate I get
"Firefox can't find the file at 
/C:/Users/rdboylan/Documents/R/R-2.15.2/library/base/html/abbreviate.html."
The page before, which did display, was 
"file:///C:/Users/rdboylan/Documents/R/R-2.15.2/library/base/html/00Index.html" 
(the link that fails is being tried with the same file:///C:/ start, 
despite the text in the error message).

Is this a bug?  Is there a way I can fix it?

2. ?'&&' produces "No documentation for ''&&'' in the specified packages 
and libraries".  This used to work.  Is this failure expected?
Actually, I just discovered it works from the main R application. The 
failure is from ESS 12.09-1 on emacs 24.2.1, both of which were the 
latest as of last week.

3. Are the manuals available as info files (for use in emacs) anymore?  
I notice the FAQ ("2.7 What documentation exists for R?") does not list it.

Thanks.
