Dear R-Devels, I am designing right now a package intended to simplify the handling of market microstructure data (tick data, order data, etc). As these data is most times pretty huge and needs to be reordered quite often (e.g. if several security data is batched together or if only a certain time range should be considered) - the package needs to handle this. Before I start, I would like to

Should functions or the user be responsible for coercing an S4 object argument containing the proper object (and thus should below be considered a bug in the packages or not)? The example is with RSQLite but the same thing happens with RMySQL, and other DBI packages. > library("RSQLite") Loading required package: DBI > m <- dbDriver("SQLite") > con <-

Hi I''m loading a gem on demand but can''t find a way to spec it. Assuming rubygems is already loaded, I assumed the following would work: describe SqliteConnection, " class" do it "should require ''sqlite3''" do Kernel.should_receive(:require).with("sqlite3") SqliteConnection.new end end Unfortunately

Dear R Experts, I have written a following function :- myfunction<- function(servername,dbname,dbtablename){ library(RODBC) channel <- odbcDriverConnect("driver=SQL Server;server=servername") initdata<- sqlQuery(channel,paste("select * from dbname .. dbtablename")) return(dim(initdata)) } I have written this function which has input parameters like servername

Hey everyone, I don't have a question. Instead some helpful advice with things I've learned from trying to connect 'R' to databases using RODBC. ROBDC is a very handy tool that, once you have everything fixed up nicely, is a great way to have scripts run fairly autonomously, safe in the knowledge that data isn't accidentally messed up. But I was fairly ignorant

Hi All, I'm having problems getting results from a PHP file. This is what the CLI is showing. -- Executing [111 at internal:1] AGI("Console/dsp", "GoTalk.php") in new stack -- Launched AGI Script /var/lib/asterisk/agi-bin/GoTalk.php [Dec 14 11:57:25] ERROR[20260]: utils.c:1019 ast_carefulwrite: write() returned error: Broken pipe If I run the PHP file from

I''m running a benchmark to check database performance. I don''t quite understand the results. The benchmarking code looks like this class DBTable < ActiveRecord::Base ActiveRecord::Base.establish_connection( :adapter => "mysql", :socket => "/var/lib/mysql/mysql.sock", :username => "..user..",

Hi all, I'm having the same issue as in this previous post: http://r.789695.n4.nabble.com/R-error-td4200447.html#a4209042 And as another user of Biostar: http://www.biostars.org/post/show/42562/cummerbund-isnt-managing-cuffdiff-database/#42895 Whereby I'm trying to output cuffdiff data into cummeRbund, but it appears to be having issues with connection to a database (below). Does anyone

Dear All, maybe this is something obvious, I seem to be incapable of understanding how S4 works. So, in package 'A' I defined a "summary" method for my class: setMethod("summary", signature(object="ListHyperGResult"), function(object, pvalue=pvalueCutoff(object), categorySize=NULL) { "whatever" })

Hi everybody, How can we add new contexts in asterisk realtime module? All I could figure out after googling is that a new context HAS to be declared in extensions.conf with 'switch => Realtime/@<databasetable>' under the context name declaration. This works fine as long as we are adding extensions only to this one context, but doesn't give the freedom to add new contexts for

Hi, Just get started with Rails and I''m trying to read ahead and find out whether Active Record supports auto-creation of database tables for you? Is this supported, or is the concept that you write your own database DDL to do this? Thanks -- Posted via http://www.ruby-forum.com/.

I've had 50+ people download the web components, and other than reports of compile issues, I have not heard if this collection has worked for anyone. I do plan to keep updating the * applications and the web pages, but I have almost meet all of our internal requirements and wonder if anyone else is finding it usefull. My focus has been and will likely stay on the user interface, since I have

(I am not sure if this is a bug or a request for a more understandable warning, or possible something obvious I should be posting on r-help.) I am trying to coerce an new class object to be a DBIConnection and it does not work the way I think it should: R version 2.5.1 (2007-06-27) ... > require("RMySQL") # or require("RSQLite") Loading required package: RMySQL Loading

Hi all... I am a new bie of ruby rails. i was working with some task to get a database table to be exported in to an XMLFile. I need to write a raketask for that. Can some one please help me with some good stuff having with you regarding the rake task file written to do that dbtable to xml file file conversions. Please help me with some sample code or links Thanks to all in advance --

Hi, since bigglm doesn't have update, I was wondering how to achieve something like (similar to the example in ff package manual using biglm): first <- TRUE ffrowapply ({ if (first) { first <- FALSE fit <- bigglm(eqn, as.data.frame(bigdata[i1:i2,,drop=FALSE]), chunksize = 10000, family = binomial()) } else { fit <- update(fit,

Hi I have a problem in R that I have been trying to solve but without success. I am trying to join two tables on two variables : an ID and a date (optional) that will be common between the two tables In SQL (and SAS PROC SQL) I am a frequent user of the "select" command and I am used to the following nomenclature : select a.*, b.c, b.y, b.z from table1 a, table2 b where

I am trying to use a shiny app to update records in an sqlite database. I keep running into the following error: unable to find an inherited method for function 'dbSendQuery' for signature '"src_dbi", "character"' The query I am trying to send is: [1] "update kpquestions set mrisupercat = 'Demographics - Respondent' , set mricategory =

The other day I was working on an example which used tempfile() to create file for use by the graphics device. And while I love tempfile()---as it is portable and clever and the files get cleaned by R and all that---I noticed one missing feature I would like to see: beside a starting name pattern, and an optional directory, an 'file extension' argument would be nice to have. As e.g. in

Hola Javier, si no estoy entendiendo mal, lo q deseo hacer no se trata de configurar los parametros SQL, sino solo de colocar un vector en el argumento VarTypes de la funcion sqlSave. El manual especifica esa opcion, pero no da ningun ejemplo de como usarla. *varTypes an optional named character vector giving the DBMSs datatypes to be used for* *some (or all) of the columns if a table is to be

I'm afraid I am at a loss. If the three files, app_cbmysql.c, app_meetme2.c and Makefile all exist in ../apps then a patch -p1 from the ../asterisk directory should work. The -p1 tells patch to ignore the first directory in the path to the file in the patch, -p2 ignores two directories. Another option is to just edit the apps-meetme-cbmysql.txt and split it into three patchs and apply
