Hello, I've recently discovered a persistent issue with rpanel when running R.app (2.6.1) on Mac OS X 10.4.11. tcltk and rpanel load without any apparent error, and the interactive panels appear to work as expected, however upon closing the panels rpanel has created I get catastrophic errors and R crashes completely. For the most part R manages to crash with dignity and work can be saved, but

Guys, if you define recording on queues.conf and also define a monitor_filename var on your dialplna, you can record a queue call but, isthere a way to do something with the file after the call ends? I need to move the file to some other place but I cant find where to define a command to run after a queue call finishes. Any hints?

Hi R users, I am new to using DBMS with R for large datasets. Thanks to all who responded with useful suggestion to my earlier postings about using large datasets and DBMS with R. I am writing to get some help about how to design good tables in DBMS to take full advantage of the wonderful built-in facilities in R, like labels. I am using RMySQL client. Because R makes good use of variable

Hi, if we have a file called Rscript.R that contains the following, for example: x <- 1:100 outfile = "Rscript.Rout" sink(outfile) print(x) and then we run >> source("Rscript.R") we get an output file called Rscript.Rout - great! Is there an internal variable, something like .Platform, that holds the script name when it is being executed? I would like to use

Is there any reason why AR has never supported foreign-key constraints? I can understand the lack of support for triggers and stored procedures since they are highly dependent on the database to create a wrap API around them. But this is not the case for foreign keys. This is specially important for open-source projects like Redmine/Chiliproject and Gitorious where you shouldn''t be

I've been putting together a package that defined generic methods for database access. The packages is called "Rdbi." It borrows as much as possible from existing database packages / proposals. I'd like to start a discussion about the proposed interface. Here's what I've come up with so far: # # Rdbi: connectionMethods.R # dbConnect <- function(dbObj, ...)

Hi, I need to somehow make R communicate with another remote JAVA process which provides compute services. I have control over the communications protocol, but I would like to keep it to a standardised protocol, such as SOAP, CORBA, etc. What I would like to know is, what do other people use to do this? The nature of the communications will be low bandwidth procedure calls, with little data.

In a RoR application, is it possible to have individual userids associated with particular sessions employed to establish their related connections to the postgresql DBMS backend and, if so, is this design desireable? What are the implications for performance and future deployment limitations? The idea behind this question is that in our application certain tables require that the last

Hi, i found tis message in the archive and have got the same problems ? John, perhaps you have found now a way install RPgSQL for windows2000, or anybody other ? many thanks for advance christian [SNIP] I wonder whether anyone has succeeded in building either the RPgSQL or the Rdbi.PGSQL and Rdbi packages for Windows. If so, would you be willing to share either the binary package(s) or

I'm using Samba to allow my users to store their database on a Redhat 6.1 file server. I've got some who want to shift to using Linux instead of Windows but the DBMS they use is not supported (yet... I'm told) on Linux and I'm afraid that multi-user access on different OS's are going to screw things all to high heck anyways... But that being said... Are there existing

Sorry this is going to be a bit vague, but I''ve noticed something rather odd going on with EventMachine on Linux. I''ve written something uses EventMachine to proxy HTTP to other processes. On OS X, it works great, adding only about 20% extra latency into the connection when proxying versus connecting to the original backend process directly, so a 5ms connection might now take

I''m a little confused as to how booleans work in Rails. Which is better in the database? boolean or int(1)? True == 1 and False == 0, right? Using SQLite, I tried to set a value to true inside the database but it gave me an error. MySql didn''t, so I had to switch to int(1) for it to work. Is this just how it is? --~--~---------~--~----~------------~-------~--~----~ You received

Hello, I maintain some packages in Fedora Extras for R related modules. Until R 2.2.0 I used for post processing (both after installing and removing the package) the following lines: %{_bindir}/R CMD perl %{_libdir}/R/share/perl/build-help.pl --htmllists cat %{_libdir}/R/library/*/CONTENTS > %{_libdir}/R/doc/html/search/index.txt Typically %{_bindir} is /usr/bin and

I''ve found vague mentions of various attempts at creating an ActiveRecord adapter for the KirbyBase pure Ruby DBMS, but nothing which looks like it''s actually working. Anyone know of such an adapter that is functional and available? b

Hi- I used to use "<<-" to do assignment inside a class method, and just found that now it is broken in R 2.0. For example, the following code ----------------------------------------------------------------------- setClass( "myclass", representation(x="numeric") ) setGeneric("incrXByOne", function(obj) standardGeneric("incrXByOne"))

I have two classes, Listing and Warranty. A Listing (think of it as a product) may or may not have a Warranty from a lookup table. When I want the Warranty.company for a given Listing I want to say the following: @listing = Listing.find(4) @company = @listing.warranty.company In order to do that I did the following: class Listing < ActiveRecord::Base belongs_to :warranty end and

I see some possible issues with the SQL that is being generated by the firebird adapter. Every SQL is being generated on the fly by concatenating strings. Can someone please explain why the SQL is being generated the way it is? I cannot use this in real life for a couple of reasons: 1. This introduces a security hole because a user, accidentally or deliberately, could potentially submit a

Hi, I agree that replacing data.frames for modeling functions would be too painful. Also I agree with Thomas that new class(es) for tabular data should not inherit from data.frame, and that data.frames should conceptually inherit from some other base tabular data class. At this point I'm not suggesting anything in concrete --- I haven't sorted it out in my own mind --- but I want

Hi there, I would like some advice, not so much about how to use R, but about software that I need to complement R. I've rooted around in the FAQ's and done a few searches on this mailing list but haven't quite found the perspective I need. I am an experienced data analyst in my field (forest ecology and ecological monitoring) but new to R. I am a long time user of SPSS and have
