R generates the help pages on demand.  You can tell it what port to use, 
but it's not very easy to generate fixed copies of the HTML output.

That should always be your own computer. The browser is trying to  
reach a server on itself over port 28138 and either the port is  
blocked or you don't have the documentation at that location.


The _real_ problem is likely that the server is really running on the
remote computer. Substituting the remote server name for 127.0.0.1 is
not unlikely to make things work. (Notwithstanding firewalls and the like).

It is a generic weakness of our current dynamic HTML setup, or of
current browser technology if you like. Same thing with file:// URLs --
if you try to view them in a browser and you already have a browser on
your display, but running on a different machine than the one with the
file, you get a "file not found". So when R on machine B wants to
display a help page, it sends a message to the browser to connect to R's
own server on B  by specifying a port on localhost (127.0.0.1), but if
this request gets forwarded to a browser on machine A, then it goes
looking for a server on _its_ localhost, i.e. machine A, and it isn't
there...

I suppose we could do somewhat better, but I don't feel too confident
about the various platform issues. As far as I can see, we currently
hardcode "http://127.0.0.1"; inside the help print method in
utils:::print.help_file_with_topics(), and I suspect we could make that
a user option, or try to be more intelligent about finding the machine's
own IP address.

A pragmatic way out is always options(help_type="text").

Hi

I had similar issue and it was solved by setting proxy in browser 
preferences to

do not use proxy server for 127.0.0.1

and it helped.

That should always be your own computer. The browser is trying to
reach a server on itself over port 28138 and either the port is
blocked or you don't have the documentation at that location.

via www.geektools.com and got the
information boxed below, which suggests I'm not going where I am
supposed to be going when I ask for help.

I suppose you could use that terminology, but you should check the
specification of the "browser" entry in your options(). Does the
remote server have the documentation in a library directory? Can you
get the sysadmin for that device to give you the locations of the files?

?options
options()$browser # would at least tell you where you system thinks
it should be going.

If you restrict Baron's help search to only this year's questions
containing "help server browser" you get:

I'm assuming this problem is associated with my VMware link to the
server.

Is anyone else running this type of connection through to R and, if
so, could they please advise how to remove the issue? I've been able
to bring in my data table fine, and do some commands on it, the
issue so far appears related only to help files. I'm assuming this
is because the help files call a URL that, in my case, appears to be
incorrect (whereas the R commands are not calling a URL and
therefore are working fine).

I found this earlier thread: https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=14155
however, the commentary says the bug was fixed.
