[R] New to R

[Jeff Newmiller]

This is not really a question about R... it is a question about databases because similar divisions occur in every imperative programming language that deals with databases. ODBC is a software layer that aims to create a uniform API for the programmer among different variations of SQL databases (though it doesn't entirely succeed). RODBC gives R access to that API. You have to use OS-specific utilities outside of R to link ODBC Data Source Names to specific ODBC-to-DB "drivers".

The alternatives are usually much more specific to the DB back end, with potential ability to take advantage of DB- specific features, and disadvantages of being more closely tied to that particular software.

There is a mailing list (R-sig-db) where you should ask more specific questions about how R deals with these non-R- specific APIs, but each of the R packages maps to much more extensive documentation about those APIs that you will need to be familiar with in order to make progress with them.
