starwars

The dplyr package includes a dataset called $$starwars$.$ Using this dataset,

answer the following questions using piped dplyr code:

$1.$ Which column has the most missing values?

$2.$ How many individuals in the dataset are neither male nor female?

$3.$ with a single line of code, find out how many individuals come from the

most frequent species? $($This one is more difficult$)$

$4.$ filter the dataset to only include humans, then sort by homeworld $($de$-$

scending$)$ and then by height. What are the last four rows of the resulting

dataset
