Hi,
My Fedora 11 linux (version 2.6.30.9-96.fc11.x86_64 #1 SMP Wed Nov
4 00:02:04
EST 2009) recently updated me to R-2.10.0, and help.start() is no
longer
working. I see in the release notes that R now uses an internal
web server to
autogenerate help pages. Here's what I'm getting:
IN R:
help.start()
starting httpd help server ... done
If '/usr/bin/xdg-open' is already running, it is *not*
restarted, and
you must switch to its window.
Otherwise, be patient ...
IN Firefox:
Firefox starts up, but gets a "connection refused" error:
While trying to retrieve the URL: http://127.0.0.1:11586/doc/
html/index.html
The following error was encountered:
* Connection to 127.0.0.1 Failed
The system returned:
(111) Connection refused
I have checked all my firewall settings, and as far as I can tell
the connection
should be allowed. In fact, and unexpectedly, if I try on the
command line:
wget http://127.0.0.1:11586/doc/html/index.html
the index document is returned, so I know the R server is running
OK on that
port, but apparently refusing the connection to Firefox.
Has anyone else had a similar experience or have any wild guesses
about a solution?
I had a similar experience on my IMac (Mac OS X Version 10.4.11) ---
but the error
message made some mention of ``proxies''. The problem got fixed by
adjusting
the Firefox preferences. On the Mac the appropriate set of clicks is
Advanced --> Network --- Configure how Firefox connects to the
Internet (Settings)
Then (I think!) the key was to click on/activate ``Manual proxy
configuration'', and
then to make sure that ``127.0.0.1'' appears in the window labelled
``No Proxy for:''.
This is all Mac stuff, and it's not at all clear to me that it will
translate to the
Linux setting, but it *might* give you somewhere to start. Good luck.
cheers,
Rolf Turner
