Tidy evaluation, quo, and !!: Learning the R Tidyverse

The ability to provide column names as strings is incredibly valuable when doing programming or building shiny apps. When programming we will often be returned a string that we want to use in a tidyverse expression, and rather than meddle with non-standard evaluation we can simply provide the column name to verb_(). In Shiny applications, control elements like selectInput return their inputs as strings—and so are again most effectively used with verb_() functions.
