Hello... After installing the precompiled version of R 2.1.0 (congratulations to the R Development Core Team) for Windows XP (Service Pack 2), I'm having problems with the "odbcCloseAll" and "odbcClose" functions within the "RODBC" package. I get pretty much the same error message for both functions: odbcCloseAll() produces: Error in .Call("RODBCCloseAll", PACKAGE = "RODBC") : "C" function name not in DLL for packa...

I have several hundred Excel 2007 data files in a folder. I would like to read every file in a single given folder using a loop. I have searched the FAQ, the forum archives here, other or older R boards and the R Import / Export documentation, and have asked some very knowledgeable R users without learning of a solution. I hope someone here can help. I understand that the most common

Hi, I'm running Rgui v2.4.0, RODBC v1.1-8, and psqlODBC v8.2.0002. Whenever I do the following chan <- odbcConnect("mydatabase", uid="admin") # connection to a postgresql db on a linux box tmp <- sqlQuery(chan, "select * from sometable;") # this is successfull odbcClose(chan) # this crashes Rgui and raises an error window containing the following MS error

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 have some questions about the RODBC package. library(RODBC) # required for those who want to repeat these lines 1st, I noticed that the following sequence does not work: channel <- odbcConnextExcel("test.xls") tables <- sqlTables(channel) name1 <- tables[1, "TABLE_NAME"] # this should be the name plan1 <- sqlFetch(channel, name1) # bang!

Hi, I am a new R user and am trying to construct a palaeoenvironmental transfer function (weighted averaging method) using the package rioja. I've managed to insert the two matrices (the species abundance and the environmental data) and have assigned them to the y and x values respectively. When I try and enter the 'WA' function though, I get an 'Error in FUN' message (see

Dear all, platform i386-pc-mingw32 arch x86 os Win32 system x86, Win32 status major 1 minor 2.3 year 2001 month 04 day 26 language R I wrote the following to import tables in different database formats (Access, Visual FoxPro, etc.): getTable <-

Hi, Using the fast=F option, sqlSave saves without matching column names. It looks like a bug to me.......... Here's a simple (artificial) example. ----------------------------------------- Create a dataframe and save it to a database table "test" as follows: df <- data.frame(T=1, S=10) sqlSave(channel, df, "test", rownames=F) The table now looks like T S 1 10 If

Hi, I am hoping to use the RODBC package to write a dataframe to an Excel .xlsx file. The dataframe contains at least one field with character elements that exceed 255 bytes, which appears to be the cell width limit in Excel. Below is example code and the warning message received: library(RODBC) d <-

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

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);

Dear R-experts, I have got an excel file as attached. I imported it successful with the commands: library(RODBC) channel <- odbcConnectExcel("data2.xls") tables <- sqlTables(channel) # list the names of the spreadsheets name1 <- tables[1, "TABLE_NAME"] # get the name of the 1st spreadsheet plan1 <- sqlQuery(channel, sprintf("select * from [%s]",

..., but if I put a loop around the code so that I fetch data from a different source table, and then save it again to a different destination table, the code crashes. It is either the final sqlQuery or sqlSave queries. I have no idea why it is crashing. As an aside, I also have trouble with the odbcCloseAll() command - R tends to crash with that, also. I'm running this on Windows XP, Access 2003, R version 2.7.2 Any insights would be greatly appreciated! The condensed version of the code is below. # import the libraries library(RODBC) # Close any existing connections odbcClo...

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

Hello, I would like to call a function that can take infinite time to be executed in some circumstances (which can not be easily detected). So, I would like that once the function is being executed for more than two seconds it is stopped. I have found documentation for timers but i did not found how to "kill" a function. Moreover, I would like not to change the function code (it should

After importing data from Excel through ODBC. In the inclusion dataset, class(inclusion$Value) is coming as factor. After filtering the data, length(inclusion$Value == 0),the answer is coming as 4879, but actually Value contains only 225 rows. So how can I get the length as 225. Can anyone help? setwd("D:/AZ") library("RODBC") cdb_cnct <-

Hi, all. I'm new to R. I've been a SAS programmer for 20 years. I seem to be having trouble with the most basic task - bringing a table in an *.RData file into a data.frame object. Here's how I created the *.RData file. library(RODBC) db <- odbcConnect("*******") df <- sqlQuery( db , "select * from schema.table where year(someDate)=2006" ) save(

The first column in my Excel sheet has mostly numbers but I need to treat it as character data: > library(RODBC) > channel <- odbcConnectExcel("U:/efg/lab/R/Plasmid/construct list.xls") > plasmid <- sqlFetch(channel,"Sheet1", as.is=TRUE) > odbcClose(channel) > names(plasmid) [1] "Plasmid Number" "Plasmid"

Hi everyone, In relation to the RODBC odbcClose bug which was fixed back in the changelog below: Version: 1.2-3 (2008-01-24, released) * Plug a memory leak in inRODBCClose (closing a connection), reported by Stephan Henne. * Use translateChar() on character data sent in.
