Dear R-users. I'm struggeling to fix the superscript of a label of a figure axis. For some reason R doesn't recognize the "hat" symbol. plot(1,1,xlab="ligth intensity (PAR)",ylab=expression("mass Pteridium rhizomes" (gr/0.25m^2))) A very similiar scriptline does not give any problem at all: plot(1,1,xlab=expression("balsa plot basal

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:

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

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

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 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.

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

Dear list, Being new to both the postgres database, ODBC and the RODBC interface, I am somewhat confused by some of the problems I am experiencing trying to connect R to the database. Whai I am trying is basically the example part of the help file for the sqlSave function: > library(RODBC) > odbcConnect("theodor") -> channel > data(USArrests) > sqlSave(channel,

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 <-

Under WinXP, I have a system DSN called foo. It has stored username/password information. (I can click Configure in ODBC Administrator and then Test Data Source connects to MySQL without me re-entering data.) Using RODBC, I can connect to the same database. But when I do odbcConnect("foo"), I get a window that requires me to re-enter username/password information. It seems like

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, I want to leave pwd blank (to comply w/ company security protocol) and just be prompted by the driver-specific data source dialog box to enter the password after. But for some reason it is not working. R Version: "R version 2.15.1 (2012-06-22)" R Studio Version: 0.97.312 OS: Windows 7 library(RODBC) ##HERE IS THE CODE THAT DOES WORK ##my DSN, UID, PWD is entered something like

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

Hi, I'm trying to connect to a Teradata database via RODBC on a Linux 64 machine (Red Hat Enterprise Linux 5). The ODBC driver is properly configured and queries sent via unixODBC's isql tool work properly. However, this is what happens when I try to connect via RODBC: > library(RODBC) > conn = odbcConnect("thedsn", uid="theuid", pwd="thepass") ***

Hello all, I have a strange / interesting problem that might be 'R' settings themselves, or it might be something with the OS. I am using the RODBC library. I have a script that goes out and, before making a query for a big data set, will first query for the column names of the data set. The column names could sometimes be quite long (e.g., "Time Background Estimation

Hello Experts, how can I use variables in the RODBC environment. Example which does not work: Thanks for your help. Thorsten pn <- '39R5238'; library(RODBC); odbcobj <- odbcConnect("SQUIT21C",uid="muehge",pwd="xxx"); sql <- "select u.unitid, from test where part in ('pn') "; parameter <- sqlQuery(odbcobj,sql);

Hello, I successfully used RODBC very frequently, but after having updatetd to R 6.0.2, the current RODBC-Version gives me some problems. After connecting to my Oracle-Database via odbcConnect("") (or the necessary information) I receive a much longer output than usual: RODB Connection 0 Details: case=nochange DRIVER={Oracle in OraHome90} ... with all the details. Previously,

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

Hello all, I am having trouble running a count function in R using RODBC to query a table I created in Oracle. It may very well be that my SQL coding is incorrect; I just started learning it. But if someone could point me in the right direction or tell me if I am going about this the correct way that would be greatly appreciated! The script I have right now is: >require(RODBC)
