Summary

Instruction

Now we come to one advantage of dplyr over base R: dplyr allows us to exclude columns by name. We simply replace the position number with the column name. So to select all columns except continent, we'd write:

select(countries, -continent)

Exercise

Select all columns except population from countries.

Stuck? Here's a hint!

Type:

select(countries, -population)
