Tidyeval Principles #69

Closed gadenbuie closed 5 years ago

gadenbuie commented 5 years ago

When to use tidyeval and NSE?

  1. Columns that are expected to exist in the input data and are used in computation should be unquoted.

    fcds %>%
 separate_age_groups(age_column)

  2. Columns that are created, added, or (possibly) overwritten are character strings.

    # good
fcds %>%
 separate_age_groups(age_column, age_min = "age_low")

# bad
fcds %>%
 separate_age_groups(age_column, age_min = age_low)
