An example is the janitor::clean_names function I like to use for standardizing the column names on a data.frame.
However, the tidyverse is really serious in terms of api consistency and functional style, with pipes and purrr's functionalities. The unixy style of base R is unproductive in terms of fast iterating an analysis. Also, the idea of "everything in a data frame" (or tibble, with list columns and whatnot) together with the tidy data principles really takes the cognitive load off to just get things started.
