Basic Vector (Loops)

The following code gets just the genus from strings that are scientific names and capitalizes the first letter of the genus name. The str_extract and str_to_title functions are from the stringr package, which is great for working with strings.

waterbird <- "cygnus olor"
waterbird_genus <- str_extract(waterbird, "\\w+")
waterbird_genus_cap <- str_to_title(waterbird_genus)
print(waterbird_genus_cap)

Modify the code to loop over a vector of multiple scientific names and print the capitalized genus names to the screen one line at a time, using the following vector:

waterbirds <- c("cygnus olor", "aix sponsa", "anas acuta")
