I am using R 2.0.1 Patched on Windows 2000. I have created a binary package for Windows that builds, checks, installs and works without errors. In some of my .Rd files, I have links to functions in the standard packages supplied with R as well as links to others in add-on packages that I have installed. For instance, one .Rd file has the following snippet: \seealso{

Hello, I created a table in MySQL with this command CREATE TABLE example (pk INT NOT NULL AUTO_INCREMENT,PRIMARY KEY(pk), id VARCHAR(30),col1 VARCHAR(30),col2 VARCHAR(30)) ### In R, I can connect to this table: library(DBI) library(RODBC) chan <- odbcConnect("MySQL51", uid="root", pwd="xxx") first <- sqlQuery(chan, "select * from example")

Hi! I am trying to retrieve data from a MySQL Database using RODBC with the commands odbcConnect and sqlFetch. There are different data files in the database and in some cases it works without any difficulties. Nevertheless I get an error with some data files. Since I'm not familiar with MySQL I hope to get some ideas here. My code looks as follows: myconn

I'm trying to pull data from multiple MS SQL Sever databse in R. I can access the databases one at a time, but the tables are to large to pull the entire tables then join then in R. So I need to do a SQL join that will join the tables from the each of the databases. How do I combine the connection so that I can implement it in my sql query below. I'm currently getting the following error:

Hello Users: I'm using R version 2.0.1, and having problems with RODBC. Everything works fine when I use Rgui, but when I try to use Rterm and issue the commands library(RODBC) con <- odbcConnect("MySQL", "test") I get the following error: Error in sqlQuery(con, str) : first argument is not an open RODBC channel In addition: Warning messages:

I am trying to restart on R after 2 months stop. Start with previously functioning procedure: "ch<-odbcConnect("dBase Files")" get "Warning message: ODBC connection failed in: odbcConnect("dBase Files") " I have tried unsuccessfully different working directories. The only change I see is that I am working with a new login account on the same machine.

Hi I know that it is very easy to import data from a dbf file to R, by saving the data as csv, for instance. However, I have several hundreds of files to do that. So, I thought of using RODBC to read the dbf files and save it as data.frame. However, I cannot even start (this is my first time using such package): > library(RODBC) > bdades <- odbcConnect("prova.DBF") Warning

Apologies, but after a fair amount of digging, I still only have a foggy understanding of the cause of this problem, due to my own ignorance. I hope to use RODBC package to connect to an Access DB when running 64 bit Win7 (R version 2.11.1, 64 bit). I have successfully done this before on a winXP machine. Currently I am unable to establish a connection using odbcConnect("") (I am

I am trying to connect sybase sql databast from R using RODBC pkg and getting the following error ( i chnaged names to my*** but when I actually execute it, I put down names explicitly not calling some character strings) > channel = odbcConnect(dsn='mydsn',uid='myid',pwd='mypasswd') Warning messages: 1: [RODBC] ERROR: state IM002, code 0, message [iODBC][Driver

Hi all, I'm having trouble connecting to an oracle database using RODBC under winXP. Unfortunately I can't really send a reproducable error as the initial call to odbcConnect seems to hangs R and I have to kill the session. I have been using RODBC to sucessfully connect to an MS Access DB that has tables linked through to the oracle database in question and that seems to work OK but it

I use RODBC as my conduit from R to SQL. It works well when the tables are stored on one channel, e.g., channel <- odbcConnect("data_base_01", uid="....", dsn="....") However, I often need to match tables across multiple databases, e.g., "data_base_01" and "data_base_02". However, odbcConnect() appears limited insofar as you may only query

Hi, I have a data base in oracle and need to link R using ODBC. When i use the command odbcConnect a dsn is needed. I would like to create a dsn.Do you know how can i do it? Thank you. Margarida,Portugal

I'm looking for an optimal approach to access Oracle databases via RWeb applications. I'm new to R but familiar with programming functions and web pages for the S+ Statserver. I'm now going through the motions of migrating S+/Statserver applications to R/RWeb as a feasability exercise. I can access databases using ODBC directly in R or S, and using Statserver, but I have not succeeded

I am using RODBC and "odbcConnect". I have successfully used odbcConnect to extract "modest" amounts of data from SQL. For convenience, (and maybe speed?) I wish, if possible, to extract larger amounts of data in a single query. (I am running R2.6.0 under a machine running Windows Small Business Server with 3mb of RAM. I run gc() prior to attempting the query. I have

Hello Folks, I do hope this is the correct place to post (and not in R-SIG-DB). I have spent the better part of a day searching for an answer to this question, and have yet to resolve it. I am trying to query an .accdb Access database (with 32-bit Office 2007 currently residing on the machine) with 64-bit R via RODBC. There seem to be some conflicting accounts as to whether or not this is

I'm not sure if this problem is repeatable or particular to my machine. The following works fine - > odbcConnect("demoteam", uid = "demo", pwd = "demo") This causes R to crash - > oracle.info <- list(channel = "demoteam", uid = "demo", pwd = "demo") > demo.db.connect <- function(ora.info = oracle.info) { + channel

All, I am new in R. I found sqlSave() doesn't work for our Oracle9i. The following was the message: > sqlSave(channel, USArrests, rownames="state") Error in sqlColumns(channel, tablename) : USArrests : table not found on channel Check case parameter in odbcConnect > sqlQuery() works OK. Please help. Thanks. -MY

Hi all, I am encountering an RODBC problem in R 2.15.1 in windows 64 bit which I do not encountered in the same set up in windows 32 bit (the latest binary version of RODBC in both cases from the same depository gotten by install.packages(‘RODBC’), Oracle ODBC client software installed in 64 and 32 bit respectively) 1. The code looks like library(RODBC) credentials <-

I am having a problem with RODBC's connections. It appears that my connection to the database is closed by R automatically before I am done with it. Here is my code: foo <- function(dsn) { db <- odbcConnect(dsn) odbcSetAutoCommit(db, FALSE) data <- someDatabaseOperation(db) data2 <- someLongCalculation(data) anotherDatabaseOperation(db, data2) # This often fails b/c the

Hi R-Users, I have very recently switched from using R on windows 2000 to windows XP Professional. With XP I am having problems using the "odbcConnect("")" command. I can use the command perfectly well until I close the database channel with the command "odbcClose(channel)". When I try and re-establish connection following the close command no dialog box appears
