Maybe the package SQLiteDF could be useful for you. http://cran.r-project.org/web/packages/SQLiteDF/index.html

But since you mention that the data has 1 mio values, I think it should be no problem to read the data set "conventionally".  > (object.size(rnorm(1e06)))/(1024^2)
[1] 7.629417

Assuming that all data are numeric, the data-set should consume less than 8MB.

I hope this helps,
Roland
