Oftentimes, with just a few elegant lines of code, your data becomes that much easier to dissect and analyze. For these reasons, it is an essential and foundational skill to master for any aspiring data scientist. Often one may be surprised how some easy-to-learn functions can make the data analysis process that much more efficient. That is certainly the case with dplyr.
