The RODBC package’s `odbcConnectAccess2007` function is exclusive to Windows users. This limitation stems from its dependency on an ODBC driver for Microsoft Access, which is only available on Windows. This means that approximately 80% of R users, who operate on non-Windows systems, must seek alternative methods to connect to Access databases. Suggested alternatives include using `mdbtools` with the ODBC driver, alongside options like DBI + odbc, RODBC, Hmisc::mdb.get, or RJDBC + UCanAccess. Additionally, when downloading non-text files, it’s crucial to use `download.file(url, tempf, mode = “wb”)` to avoid errors later in the process.
