similar to: Rdbi and ODBC

Hi, I would like to be able to use R with a connection to a PostgreSQL database. I am using R 2.0.1 on windows XP. I have tried installing both the DBI and rDBI packages (which is better?) but in either case I run into the same problem - when i try to use either the dbDriver or dbConnect functions i'm told the function couldn't be found. Seems like the packages aren't installing

one more bit of information about this problem. If I start R as the user "postgres" i dont have the segmentation fault. ---------- Forwarded message ---------- Date: Wed, 5 Feb 2003 19:19:39 -0500 (EST) From: Rafael A.

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 am experiencing the same behaviour explained here: http://finzi.psych.upenn.edu/R/Rhelp02/archive/2482.html (i copied the message below) has anybody found a solution? here is the code that gives me a segmentation fault library(Rdbi) library(Rdbi.PgSQL) conn <- dbConnect(PgSQL(), dbname = "PGA") tmp <- "create table test ( expid int, name varchar(128));"

I can use the Rdbi package to connect to a PostGreSQL server fine but when I use the dbDisconnect(), I get a segmentation error and it throws me out of R. I'm using RH7.2, R1.4.1, Rdbi 0.1-2, and Rdbi.PgSQL 0.1-2. Anyone else seen anything like this and have an possible answer?

Hi, I just installed ROracle and RDBI. The connection to the database seems to work also. My problem is when I am selection rows that really exist in the database, it is returning nothing. Where should I look to see what could be my problem? Thank you very much, Mathieu > drv <- dbDriver("Oracle") > summary(drv, verbose=TRUE) <OraDriver:(6721)> Driver name:

Hello, i see packages referencing using ODBC access to databases via R, are there any packages that use JDBC to submit SQL to a database and return into a data frame? -zubin

Hello List, I would like to connect to a postgreSQL database on a remote server and I am wondering what is the best package to do that. I have just installed RpgSQL, RPostgreSQL, Rdbi and RODBC. The handiest to me is RPostgreSQL but I don't see how to connect to a remote server with it. For sure I can connect to remote server with RODBC, but since I am on a Mac OSX 10.6, I have quite

Good day, I read some data from a PostgreSQL database by a following script: library(Rdbi) library(RdbiPgSQL) # conn becomes an object which contains the DB connection: conn <- dbConnect(PgSQL(), host="localhost", dbname="BVS", user="postgres", password = "*******") query_duj_kal <- dbSendQuery(conn, "select zdroj as well, cas as date, fe2,

Dear list members, 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 instructions about how to set up the configure scripts? My preliminary efforts to get things going under Windows 2000 haven't met with much success. Thanks, John

To get the Rdbi/RdbiPgSQL 1.0.1 interface from BioConductor functional, I would like to suggest some fixes. Find patches and the updated packages here: http://mpa.itc.it/markus/tmp/rdbi/ Changes Rdbi: - fixed load of RdbiPgSQL (wrong name) - fixed dbConnectionInfo() (typo) RdbiPgSQL: - fixed table export to PostgreSQL - added make.names() to polish column names for R usage

Hi all, I tried to install the Rdbi_0.1-2.tar.gz and Rdbi.PgSQL_0.1-2 package. The Rdbi_0.1-2.tar.gz installed fine but the Rdbi.PgSQL_0.1-2 had some problems. The compilation routine tried to find a header called libpq-fe.h but did not find it in the standard locations. I searched through the computer but did not find a file called in this way either. What should I do to successuffly

I cannot get a database connection in R to my MS SQL Server database. In S-Plus 6.2 I have used the following successfully: rawdata <- importData(type="DIRECT-SQL", user="xfl2", password="xfl2", server="rinnycs0059", database="xf", table="", sqlQuery="select * from testTbl") In R I have tried both DBI and RSQLite, but

Hi, I'm trying to establish a connection to a MySQL database, and am using the rodbc package for it. This is in a GNU/Debian Linux box, with the corresponding Debian unstable packages. I can login to my MySQL databases from any shell and directory, so the problem is probably not there. Here's an example of what I'm doing: R> odbcConnect("test",

Hello, I know that the topics of using large datasets in R vs. SAS, using PostGreSQL vs MySQL, and using databases with R have been discussed extensively on this list and elsewhere. However I hope that I have a slightly new combination of the questions here. I am doing my PhD research on a large dataset and trying to decide whether to use PostgreSQL or MySQL with R, or simply use SAS, to

Hi all, I would like the following code to work, but it doesn't: library(DBI) library(RODBC) m <- dbDriver("RODBC") # Example for dbConnect(DBI), causes error m <- dbDriver("ODBC") # Example for DBIDriver-class(DBI), causes error The errors are: Error in do.call(as.character(drvName), list(...)) : could not find function "RODBC" (substitute

I usually work with R on a windows querying data through RODBC from a postgresql db on a freebsd machine on my offcie lan. Now I have the chance to use R also on a linux gentoo client box and to connect to the same db. I know that I can install the unixodbc stuff and stick to RODBC, BUT my question is: Is there any more 'linuxish' way of querying a postgresql server from a client?

Hi, I am relatively new at R, but I would like to be able to directly access my MySQL and PostgreSQL databases from R. I have been looking around CRAN and searching through Google, however I am not sure what are the best options. I have seen DBI - not sure how this works Rdbi - not sure how this works Rdbi.PgSQL - can install, but fails on trying to load RODBC - cannot

Hi, I'm trying to use R's DBI interface but it appears to be broken. I am using R 1.8.0 on Linux, and have just installed DBI 0.1-6 through the command 'install.packages("DBI")'. Installation went fine, but now when I try to do a simple dbConnect(), it won't do anything besides complaining about an internal error: > library(DBI) > dbConnect(anything) Error
