concurrent requests (Rook, but I think the question is more general)
This question involves Rook, but I think the answer will be general
enough that it pays to post here. At any rate, I don't know enough to
know whether this is a Rook only issue or a general R issue.
Here's what I'd like to do (and indeed, have code that should do this):
1. Start R, Rook
2. Start an analysis via a HTTP request to Rook. This analysis uses
.Call() to some compiled C

paths and Rook problems only in OSX CRAN binary package?
Hi everyone,
I'm trying to diagnose a problem in my R package, but it is a little
tricky since it seems to occur only with the Mac OSX CRAN binary build.
My package starts a Rook server and opens a browser. On my own system
(details below), when I build the package, I have no trouble. The Rook
server starts and the page loads in the browser.
However, if I've installed it from CRAN, I

Exposing native httpd server
R has a native HTTP server that is used for serving R help pages
interactively, at least on the loopback device (127.0.0.1)
But all of the working are internal, not exposed to user and not documented.
This is quite shame since the server seems to be fully capable of
handling basic tasks,
be it serving static websites or even interactively processing queries.
This was previously noticed by

Exposing native httpd server
Ji??,
in a sense there are two quite different issue that you are touching upon. On one hand, your request for exposing the http server is something I was pretty much expecting. In order to judge the appetite for it I have included the support for custom handlers back then as inofficial API specifically so that if anyone cares we could work on refining it (really only Jeff and Hadley ever asked

Start R from bash/bat file and end in interactive mode
I have a r-script (rook.R) that starts a Rook server. To present users
from having to start R and type in source("rook.R"), I want to create
a bash script and bat file that starts R and sources the script.
However, to keep the Rook server running R should not close after
running the script and stay in interactive mode. This proves more
difficult than expected.

Exposing native httpd server
I absolutely appreciate the desire for minimalism. On the other hand
Rserve has no dependencies other than R >= 1.5.0 (!!!), so you would in
any case be cutting your dependencies way down (`servr` has 16 recursive
dependencies of which 5 seem to be base/recommended, presumably this is
where your count of 12 came from; `Rserve` has none).

Exposing native httpd server
Dear Simon and Jeroen,
thank you for your answers. I have to reiterate that I am out of my
depth in here. My knowledge of http is clicking links and not much
beyond that.
I will definitely look into `webutils` and `Rserve`.
One of the reason why I brought this issue is that I have a static site
generator that uses the pkg `servr` to serve the static site locally,
before I push it to github

regularly lattice & neighbors
Dear R-users,
Is there a procedure to identify neighbors in a regular lattice using either a
"rook" or a "queen" criterium? To be more specific, suppose:
My lattice:
1 2 3
4 5 6
7 8 9
"Rook" Neighbors
1 has neighbors 2,4
2 has neighbors 1,3,5
...
5 has neighbors 2,4,6,8
"Queen Neighbors"
1 has neighbors 2,4,5
2 has neighbors 1,3,4,5,6
For each case,

Custom helpers for list of options?
Hi all,
I have a model that "belongs_to" many other models, many of those
models are just list of names, like country, state, city, profession
... I read about the country_select helper.
Is better to have all those tables or use custom helpers? what the rails way?
Thanks.
For example : http://pastie.caboo.se/104092
