Summary

Instruction

So how do we use the results which determined missing values? We can simply subset rows that don't have missing values, like this:

census2017_clean <- census2017[complete.cases(census2017), ]

Note: After the comma, we leave a blank space. This tells R to include all columns.

Exercise

From the census2018 data frame remove rows with missing values and assign the result to the census2018_clean variable.
