Thank you for sharing this clear and concise explanation. I just started using R at a new company after many years of experience in SAS (under previous companies), so this is very helpful!
Glad it was helpful! I hope to jump back into using R more often. It's hard to keep up with so many technologies and languages! Are you enjoying R so far? The syntax must be very different than SAS.
Thank u very much for your time and well explanation sorry to ask but I have an issue here which is to create inner, outer, left, right join but my 2 data frames don't have a similar column like in your case, they have different column names. would appreciate it if u answer me back on what to do. Thank u very much.
