Dear useRs, Rook is a new package that does three things: - It provides a way to run R web applications on your desktop with the new internal R web server named Rhttpd. Please see the Rhttpd help page. - It provides a set of reference classes you can use to write you R web applications.

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

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

Hi All, I am trying to start R Server to run some Java Script in my local machine using the library, 'Rook'. I use Windows 7. And my codes are following, > library(Rook) > myD3dir <- 'D:\\STUDIES\\Java script\\d3-master' > s <- Rhttpd$new > s$start(quiet=TRUE) and i get the following error for the above line, Error in s$start : object of type

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. I tried various

Hi, When people try and break into my system from the internet I get lots of messages like: Nov 14 19:08:13 rook sshd[6333]: Failed password for invalid user guest from 210.83.48.238 port 40811 ssh2 Nov 14 19:08:19 rook sshd[6338]: Invalid user admin from 210.83.48.238 Nov 14 19:08:19 rook sshd[6338]: Failed password for invalid user admin from 210.83.48.238 port 40920 ssh2 Nov 14 19:08:24 rook

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,

All: Using gWidgetsWWW, I'm in the process of designing a website that will provide users with a GUI to interact with various datasets. As part of that, I want to provide users the ability select particular variables (via combo boxes) that will then result in summary (text) output being returned to the webpage. Think of it as their choices ultimately result in a one- or two-way table being

Hello I just read this article about a kid in England who built a box with a 3G SIM card: www.dailymail.co.uk/sciencetech/article-1394448/Doorbell-tricks-burglars-thinking-youre-home-invented-schoolboy-Laurence-Rook-13.html When someone rings your intercom, the box will call your cellphone so you can answer just like you were home. I don't know anything about electronics and would like to

I have a couple of packages (?fiery? and ?reqres') that uses a mock of a rook request for their examples. The mock is an R6 object containing a rawConnection, along with a finalizer that closes this connection when the object is removed. So far so good. I?ve recently been getting CRAN errors due to the rawConnection not being closed in examples > cleanEx() Error: connections left open:

Hi, I met tough problems when calling R in PHP. I have tried several ways, but none of them succeed.  first of all, I tried Rserve, but I failed to connect to it. Then, I tried cmd.exe. I get the result when I use" R CMD BATCH --vanilla..." in cmd, but I have no idea how to call cmd in php. I know "system()" is good to call other systems, I triedbut I get no result in my html

How do you specify matrix location a[i,j] (or a[i-1,j], etc.) in a "for" loop? I am looking for a flexible method of indexing neighbors over a series of lags (1,2,3...) and I may wish to extend this method to 3D arrays. Example: Data matrix > fun [,1] [,2] [,3] [1,] 1 5 9 [2,] 2 6 10 [3,] 3 7 11 [4,] 4 8 12 For each element a[i,j] in

Hi all, I need your opinion about using R-Rapache to build a knowlegde base to bioinformatics field. I have copious amount of genotype information (some few million records) and would like to store it in MySQL database. Then, using RMySQL connector I would like to use it for further analysis using R over a web interface. The web interface which I am thnking off, just does not serve the purose of

I am trying to set up a RApache server on my Ubuntu 8.04. I have installed apache2, R-2.7.0, and the RApache plugin. Both Apache and R seem to work fine, but whenever i try to use the plugin i get this error: C stack usage is too close to the limit. I have tried to recompile apache2, R, and RApache, but i keep getting the error. The weird thing is, i had exactly the same problem when i installed

Hello, I am working on a web system (php) that uses R in the backend, and we need some basic fast encryption/decryption for the underlying mysql database that can be used by both R AND php. It does not need to be top-of-the-line, but just provide some basic level of fast encryption/decryption. Any suggestions? Thank you, Ramiro [[alternative HTML version deleted]]

Hi, this is Charlie and I am trying to embed R in my apache server. However, I am having problem with installation. The R projet says that we can install add-on package with command $R CMD (rapache.0.1.4.tar.gz). However, I try to use it in command windows (windows xp) and an error shows. Please tell me when I can use the command (in c?? or in the same folder with the file). thx. [[alternative

dear r-community, currently i have a workflow as following: data in online-MYSQL-database via .csv into R for analysis, results back to mysql. generating graphics for reports also. that's ok, but i need some process-optimization. i'd like to run r directly on the webserver. analysis should work automatically, after the appropriate r-script was selected in a browser-gui for R. until
