Hello all, I have a large database (~100MB in 13 relational files) that made its way to me in two formats. The files were sent in both SAS xport and STATA, thanks, I am told, to stat-transfer. The two files, ostensibly, contain the same data, just in different formats. My goal: Move these files to MySQl without the help of SAS or STATA (which I do not have). The tools I am using are: 1.

I am using R 2.8 and the latest versions of RMySQL on a Windows XP 64 bit machine. I was wondering if someone could help me figure out how to use dbWriteTable without inserting \r into my table.
