Hello, Attached is a mail regarding question how to insert Date field using ROracle package. I am stuck with this problem and appreciate receiving help from gurus on this list. Code used mainly is: library(ROracle) ### --- Version 0.53 drv <- dbDriver("Oracle") con <- dbConnect( drv, "user/passwd") d <- data.frame(CDATE = "2004-03-10 10:12:00") ps

Dear List, What is the way in R to plot a graph having date time (e.g. format 12/31/2002 13:12) in the x axis and numerical value (e.g. temperature) on the Y-axis ? I could not get 'plot()' to do this as X axis values are non-numeric. 'bwplot()' sorts the date values and thereby changes the order of the dates and of Y. The date/time values have to be shown on the X-axis as tick

R-help list, I ported some R code from MS Windows PC to sun-solaris. Both do queries on the same MySQL database. PC version of R is 1.6.1 and solaris version is 1.6.0. I use RMySQL_0.5-0 (on solaris) and RODBC 1.0-1 on PC to connect to MySQL. The PC version took about 65 mins. to run wheras the Solaris (SunOS 5.7) version took 375 mins. (> 6 hrs). R and RMySQL are resident on the same host

I am trying to compute the periodicity of a time series. I would like to know which function in R does it. Also, how do I plot a Enright / Chi-square periodogram using R ? ( Enright, J.T., 1965, Journal of Theoret. Biol. 8,426-468) Greatly appreciate your help.

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 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:

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

Hi I am trying to use RODBC in R installed on Windows to access MySQL database (on a linux box). I set up a DSN and specified this DSN in R as follows library(RODBC); channel <- odbcConnect("mysqldsn"); RODB Connection 5 Details: case=nochange PORT=3306 ........ Although this seems to connect properly, running any command yields NO results. i.e. sqlQuery(channel, "show

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,

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

When I am connecting to the server via ODBC I got the following error. >library(RODBC) channel <- odbcConnect("my server", uid="***" , case="*****") Error in switch(case, toupper = case <- 1L, tolower = case <- 2L, postgresql = case <- 2L, : Invalid case parameter: nochange | toupper | tolower | common db names How to fix this error? Thanks --

All When I read data into an R variable x using RODBC command: x <- sqlQuery(channel,"select a, b from tabl",as="data frame") and view x, I get 3 columns the first one being the index of the rows in x. What options do I use in sqlQuery so as not have the index in x ? How do I get rid of the index otherwise. For some functions like princomp (and boxplot) for

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

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

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 <-

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

R-help, Could someone in the list write as to what is the R function to perform repeated measures ANOVA and post-hoc tests ?

I have a question for RODBC users out there. I have used the package with good results for some time. However, I have just switched from an OpenLink proprietary driver for MS SQL to the FreeTDS driver (I think it is MS SQL Server 2000 I'm connecting to if it matters). I was/am running them from unixODBC on a Linux Client. I think I have it set up fine since I can use "isql"

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
