When working in Base R, there are some situations where you stop and wonder: “Why isn’t there a function to do that?” For example:

- Why isn’t there a function in Base R to sort a data frame by multiple columns?
- Why isn’t there a function in Base R to get the path of the current program?
- In Base R, why is there no infix operator for concatenation?
- Why isn’t there a function in Base R to add/modify data frame labels?

The answer to all of the above questions is that there should be. The purpose of the common package is to encapsulate these types of functions, and provide them to R users in a lightweight package. These functions are particularly useful for package developers, who might want to add these capabilities to their package without creating dependencies on tidyverse.

If you have ideas for more common functions, please submit your suggestion to the github issue list.
