Although the principle was meant to be far grander than that, theres plenty of merit behind this slight misinterpretation. R, like S, is designed around a true computer language, and it allows users to add additional functionality by defining new functions. Both functions complete the same task and the benefit of using %>% may not be immediately evident; however, when you desire to perform multiple functions its advantage becomes obvious. For example, we can pipe into a linear regression function and then get the summary of the regression parameters. reddit
