Merging dataframes

Hi, May I please ask how I do the following in R. Sorry - this may be trivial, but I am struggling here for this. For two dataframes (A and B), I wish to identify (based on a primary key-column present in both A & B) - 1. Which records (rows) of A did not match with B, and 2. Which records of B did not match with A ? I came across a setdt function while browsing, but when I tried it, it says - Could not find function "setdt". Overall, if there is any way of doing it (preferably in some simplified way), please advise. Many thanks in advance. regards, Tito [[alternative HTML version deleted]]
Dear Tito, Please provide your R-code so we can reproduce your data (and your setdt-error). Best, Eivind K. Dovik Bergen, NO
