[R] Data source name not found and no default driver specified
I'm stumped. When trying to connect to Oracle using the RODBC package I get an error: *[RODBC] Data source name not found and no default driver specified. ODBC connect failed.* I've read over all the posts and documentation manuals. The system is Windows Server 2003 with R 2.81. and the latest downloadable RODBC package. The Oracle SID/DSN is mfopdw. I made sure to add it to Control Panel->Administrative Priviledges->Microsoft ODBC system/user DNS. I've also tried the following in no particular order: 1.) Turn on all oracle services in control panel->administrative priviledges. 2.) Checked tsnnames.ora for SID. 3.) Add microsoft ODBC service to Control Panel services for SID 4.) Use Sqldeveler to test connection another way besides R (It was successful) 5.) channel<-odbcDriverConnect(connection="Driver={Microsoft ODBC for Oracle}; DSN=abc,UID=abc;PWD=abc;"case="oracle") received error drivers SQLAllocHandle on SQL_HANDLE_ENV failed one time; another time I got the error that Oracle client and networking components 7.3 or greater is not found. 6.) tnsping mfopdw lsnrctl start mfopdw tried to add oracle/bin to path Nothing is working. Please advise.

[R] Error using 32-bit R and RODBC package on 64-bit Windows Server OS with R version 2.10
I am receiving an error when trying to connect to the Oracle Database using RODBC on a 64-bit Windows Server OS. The version of R is 2.10.0-win32.exe Is this the wrong version. Does RODBC only work with 32-bit ODBC drivers? 've read over all the posts and documentation manuals. The system is Windows Server 2003 with R 2.81. and the latest downloadable RODBC package.

Re: [R] Error using 32-bit R and RODBC package on 64-bit Windows Server OS with R version 2.10
Now that I know RODBC only works with 32-bit ODBC drivers this explains the problem I was having. The system has a 64 bit ODBC driver is definitely installed. I can tell because when you go to system32 folder and click on odbcad32.exe it goes to the Microsoft ODBC manager where I can select the driver installed for the 64-bit Oracle system. The system32 folder contains the 64 bit driver for ODBC. When I go to the syswow64 directory and click on the odbcad32.exe it does not take me to the Microsoft ODBC manager. Instead I get this error: Navigate to C:\Windows\syswow64\odbcad32.exe 2.) Select System DSN 3.) Add "Microsoft ODBC for Oracle" I receive this error: The Oracle(tm) client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version 7.3 (or greater) client software installation. You will be unable to use this driver until these components have been installed. I don't believe the 32-bit ODBC driver is present. What is the best way to tell if the 32-bit Oracle client software isn't installed and I'm wondering if anyone has experience to install it on a 64-bit system and call it from RODC?

[R] Missing/Incomplete Data Study
Hi, I have a project where unsupervised learning failed to produce rules using Weka. I wanted to know if there are any tools in R that can be used to assess how well timestamps of event, task, load, and hardware logs for completeness or missing and incomplete data to be able to know whether it impacted our unsupervised approach. Please advise.

Thank you for the link to the 32 bit Windows Oracle downloads for the Instant Client. That solved the problem. I'm now able to connect to Oracle database from R using the RODBC library.
