We can remove rows using the != operator. For example, to remove Florida, we would do this:

Create a new data frame called no_south that removes states from the South region. How many states are in this category? You can use the function nrow for this.

We can also use %in% to filter with dplyr. You can therefore see the data from New York and Texas like this:

Create a new data frame called murders_nw with only the states from the Northeast and the West. How many states are in this category?
