[R] New light on help.start() search applet problem

[mikalzet@libero.it]

On Mandrake systems the help.start() search applet doesn't work for any 
combination of mozilla and java I've tried; it also doesn't work with any 
other browser except for netscape 4.7 series. Something analogous, 
I'm told, happens with Debian but not with RedHat ...

I've discovered something interesting today: if the address URL in 
mozilla is:

file:///home/user/.R/doc/html/search/SearchEngine.html

the search applet doesn't get inited, but if I change this to:

file:///usr/lib/R/doc/html/search/SearchEngine.html

it works perfectly.

So it looks as if this is a problem mozilla has with .R symlinks ?
Or with permissions ? I propend for symlinks as I've noticed another 
strange thing: if, as a normal user, I open a graphical console and su to 
root, then start R as root, help.start() will work with netscape 4.78, but 
not with mozilla ... mozilla will not start, complaining about 
/root/.R/.../index.html not existing.

.R directory and subdirectories have 755 permissions, the relevant 
symlinks 777, the permissions of files in /usr/bin/R/doc/html/search 
are 644. Changing these doesn't seem to affect things.

Hoping this may help someone find the solution.
