Species Name Capitalization with Apply (Loops)

You have some data with species names that are stored in capital letters. You want to capitalize them properly so that the genus starts with a capital letter and the other letters are lower case. The str_to_sentence function from the stringr package can do this:

library(stringr)

species <- "CYGNUS OLOR"
species_clean <- str_to_sentence(species)

1. Use map_chr and str_to_sentence to produce a vector of properly capitalized species names from the following vector of species names:

species <- c("CYGNUS OLOR", "AIX SPONSA", "ANAS ACUTA")

2. Replace map_chr with map to get the answer as a list instead of a vector.

3. Use map to get the properly capitalized species and the use list_c to convert the result to a vector.

Note: this exercise doesn’t technically require the use of a map function, but we’re going to use one to keep our first use of map simple.
