[R] Non-visible functions: merge.data.table

[jim holtman]

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.
