[R] Combining local data frame with external data

[omezquita]

Hi,

I have a list of IDs on a data frame and I want to extract information for
those IDs  from an external database.

I did a workaround using the "IN" clause in SQL but when the number of IDs
is big this method doesn't work.

In other words, I want to create a join between a local and a external table
using either RODBC() or any other package.

Thanks a lot for your help!

Orlando
