I am facing the same problem as well, I would like to code with following concept but wondering how to cope it. if (*mdb file exist) { add new row/col } else { add new *mdb file } ---------------------------------------------------------------------------------------------- From: Uri Shimron <UriShimron_at_optiver.com> Date: Thu 21 Sep 2006 - 13:27:35 GMT First of all,

Hola a tod en s, Tengo un problema a la hora de conectar una base de datos (*.mdb) de Access a RStudio utilizando windows 64-bit. Con el paquete RODBC utilizo el siguiente script que devuelve el error que indico: mdbConnect <- odbcConnectAccess("C:/Users/database.mdb") Error in odbcConnectAccess("C:/Users/Isa/FPI-AZTI/JUVENA/Databases/MEGASCOPE_JUVENA2014.mdb") :

I'm trying to load Affy Annotation data from an Access database into R using RODBC. This has worked fine for quite some time. The bug seems to be correlated to RODBC versions 1.1-7 and later. Works fine: R 2.2.0 with RODBC 1.1-4; R 2.3.0 or R 2.4.1 with RODBC 1.1-6 Fails: R 2.3.1 with RDOBC 1.1-7; R 2.4.1 with RODC 1.1-7 or 1.1-8 Details ===== This works fine: Version 2.2.0

Hi all, I'm trying to import Microsoft Access data into R. It looks like I'm supposed to use the ROBC package, and this works fine with old Access files (those with an .mdb extension). However, lovely Microsoft must constantly update their software. Modern Access files have an .ACCDB extension. I cannot seem to coerce R to import data from such a file. Any advice? I've been using

Hi, I'm currently having some problem connect .mdb file into R. I've installed the RODBC packages and I do the code this way: channel <- odbcConnectAccess("C:/Users/Documents/XYZ") channel and it gave me this : RODBC Connection 3 Details: case=nochange DBQ=C:\USers\JieYi\Documents\NYP\IPP\GCR Driver={Microsoft Access Driver (*.mdb)} DriverId=25 FIL=MS Access

Dear Tobias, I finally succeeded in exporting my dataframes from R into Access with this script: library(RODBC) canal <- odbcConnectAccess("D:/Floristique.mdb") sqlSave(channel=canal, dat=flore, tablename="Floristique", rownames=F, safer=F, fast=F, varTypes=c(dates="Date")) odbcClose(canal) My problem in exporting my dataframe "flore" seems to

Dear all, I'm trying to connect to an MSAccess database (ArcGIS personal geodatabase). I keep getting an error about the channel when using sqlQuery(). However, sqlTables() does not complain about the channel and lists all tables in the database. If I try sqlFetch(), then R crashes. I'm happy to hear suggestions on how to solve this. Best regards, Thierry > MDB <-

Hi All, con <- member <- class <- list() for(i in 1:5) { con[[i]] <- odbcConnectAccess(paste("C:/Desktop/Data/source",i,".mdb",sep = '')) #read data from Access files member[[i]] <- sqlFetch(con[[i]],'member') #get table data from *.mdb files observe[[i]] <- sqlFetch(con[[i]],'observe') #get table data from *.mdb

Dear useRs, I would like to query an Access database through R based on a date attribute but, unfortunately, I fail to do so. For example, the table test_table of the test.mdb looks like: ID cd market competitor dd price 1 1 2007-11-20 atl-bos delta 2007-11-20 210 2 2 2007-11-20 atl-bos delta 2007-11-21 190 3 3 2007-11-20 atl-bos delta 2007-11-22

Hola, Tengo un conjunto de bases de datos de una encuesta industrial para diferentes años (1995-2014). Las bases de datos están en formato .mdb. A su vez, cada base de datos tiene 3 tablas con una variable "ID" común (la "llave") para vincular las tablas. Quiero realizar análisis estadísticos para analizar la evolución de ciertas variables. Quiero armar un dataframe que

Hi all: I have created a MS Access table named 'PredictedValues' through the statement below: myDB <- odbcConnectAccess("C:/Documents and Settings/Owner/Desktop/Rpond Farming.mdb",uid="admin",pwd="") sqlSave(myDB,PredictedValues,rownames=FALSE) close(myDB) But if I run the code again with new values I get the message below: Error in sqlSave(myDB,

Hi I was trying to import a dataset from access database into R My code looks like below >library(RODBC) >setwd("//STATESFPSOP1/docs/CRMPO/DEPT/Retail PD") >channel<-odbcConnectAccess("MortgagePD.mdb") >Mdata<-sqlFetch(channel, "MortgagePD") But I got error messages saying Error: cannot allocate vector of size 27.9 Mb In addition: Warning

It seems that Access needs that you surround the dates with a # symbol. You probably need something like. res <- sqlQuery(channel, "select * from test_table where market = 'atl-bos' and competitor = 'delta' and dd = #2007-11-20#") Hope this helps, Stefano -----Messaggio originale----- Da: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org]Per

Dear R-users, I am working with R version 2.10.1 and package RODBC Version: 1.3-2 under windows. Say I have a table "testtable" (in an Access data base) with 3 columns and 1 row that looks like this: X Y Z 0012345 42 42,1 The columns are of these types: X - character, Y - Long Integer, Z - Decimal. I use RODBC to get these data into R: > library(RODBC) >

Dear R-list, I am trying to import (all) frames from a Microsoft Access database as individual data frames in a fancy loop, but I'm having troubles figuring out how to use the 'sqlFetch' from the RODBS package in a loop (mostly because I can't figure out how to loop over elements (I came from stata) I would very much appreciate if anyone on the list could help me solve this

Hi, I am running the RODBC examples form the help guide. I am trying to UPDATE a table in an Access data base but I am having an error. library(RODBC) library(termstrc) path = getwd() setwd(getwd()) dbName = "data.mdb" pathdbname = paste(path,"/",dbName,sep="") accesChannel = odbcConnectAccess(pathdbname, uid = "", pwd = "")
