The function table takes a vector and returns the frequency of each element.

Example

# The "c" in `c()` is short for "concatenate," which is the action of connecting items into a chain
# The function `c()` connects all of the strings within it into a single vector, which we can assign to `x`
x <- c("a", "a", "b", "b", "b", "c")
# Here is an example of what the table function does
table(x)

#> x
#> a b c
#> 2 3 1

You can quickly see how many states are in each region by applying this function. Use this function in one line of code to create a table of states per region.

NOTE

Do not forget to first load the data as in the previous exercises!
