Non-visible functions: merge.data.table
It would help if you gave some specifics of what you are trying to do. What is the structure of the data.tables you are merging, how long did it take, have you compared the times between the base merge and the data.table merge? How fast is "fast"? What are your expectations? Can you provide a script that will create some sample data? It is hard to answer without knowing some of this information. On Fri, Dec 3, 2010 at 5:38 PM, Ryan Garner

I've downloaded the "data.table" package from CRAN and R-Forge and still can't utilize merge.data.table for faster merges. How do I make this function visible?
