Hi, I'm running Debian (Sid), Postgres (7.3.4) and R (1.8.1). I get the following error when I tri to use DBI >library("DBI") > p <- dbDriver("PostgreSQL") Error in do.call(as.character(drvName), list(...)) : couldn't find function "PostgreSQL" Is there any other package I need in order to interface between R and Postgres ?

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

Hi, i am trying to connect to a DB2 server using the DBI library. getData <- function() { driver <- dbDriver("DB2") conn <- dbConnect(driver,"server","uname","pword") data <- dbSendquery(conn, "select etc.") } When I run the function, i get the error > data <- getData() Error in

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

I am trying to follow directions at http://cran.r-project.org/doc/manuals/r-patched/R-exts.html#Suggested-packages regarding handling suggested packages with requireNamespace() rather than require(), and I have some questions. 1/ When I do requireNamespace() in a function is the loading of the namespace only effective within the function? 2/ At the link above in the manual it says "Note

Hello, I installed RGui 2.5.1 and package DBI on Windows XP and tried to connect to Oracle database which is on a Linux server.

can anybody provide a reference to a document on using DBI and what is needed to make it work? I try: drv=dbDriver("Oracle") and it complains about not finding a function. The DBI.pdf does not require anything else installed, but looking at the archive I discovered there is more stuff to be installed. This is on Solaris 5.10 with a full Oracle install, so all Oracle libs are

Hi, first thanks to Sunny Ho (and David James for the pointer) for resolving the problem of the empty rows returned from ROracle. However, I have a problem still: > library(ROracle) > ora <- dbDriver("Oracle") > con <- dbConnect(ora, user = USER, password = PWD, dbname = DBNAME) > rs <- dbExecStatement(con, "select * from USER_TABLES") Error in

Hi. I frequently use RMySQL package to interface R with MySQL databases. I was having a try with package DBI and I got the following error: > library(RMySQL) > library(DBI) > drv <- dbDriver("MySQL") > ch <- dbConnect(drv, dbname="mydb", user="myuser", password="mypasswd") > ibm <- dbGetQuery(ch,"select * from table where

Hi list, I created my rpm for Bacula 9.4.1 reading centos srpm spec files. I made a single package and not split in several packages because this is my first rpm so I created my spec file taking a cue from bacula-5.3 spec file. All works as intended, an rpm was created and installed without any not fixable issue. After installing my bacula rpm I run a test to see if all works as expected.

I just upgraded R to version 2.4.0 and now I can't install packages RdbiPgSQL. I used the same procedure I did for previous versions of R ! Actually, last time I installed RdbiPgSQL day before upgrading but now I got: downloaded 27Kb * Installing *source* package 'RdbiPgSQL' ... creating cache ./config.cache checking for PQconnectdb in -lpq... no I could not find your PostgreSQL

Hi R-users I recently downloaded RdbiPgSQL 1.8.0 and Rdbi 1.8.0 from Bioconductor to be installed under R 2.4.1. When requiring RdbiPgSQL an error message is showed as follows: > require(RdbiPgSQL) Loading required package: RdbiPgSQL Error in library(package, lib.loc = lib.loc, character.only = TRUE, logical = TRUE, : ‘RdbiPgSQL’ is not a valid package – installed <

Dear List In my short life as a beginning R-user i've encountered a following problem that i'm unable to solve myself: I have a database in MySQL containing table and field names as well as some data containing Polish accentuated characters (like ????), utf8-encoded.

Hi all, This is a potentially very stupid question about MySQL <-> R interaction, but I have not been able to solve it. I'm just trying to connect R to my MySQL databse, and gets this: > library(RMySQL) Loading required package: methods > m <- dbDriver("MySQL") > con <- dbConnect(m,group="testdb") Process R segmentation fault at Wed Oct 16 07:04:30

Dear R-helpers, I'm an absolute beginner using both R and PostgreSQL, but now I have to work with both programs. I need to connect R and my Postgres-database, but every attempt so far has failed (I tried using the RpgSQL package as well as RdbiPgSQL, the first, following this manual (http://code.google.com/p/rpostgresql/) didn't find any drivers for the database (step no. 1) whereas the
