If you don't specify the levels of the factor when creating the vector, R will automatically assign them alphabetically. To correctly map "F" to "Female" and "M" to "Male", the levels should be set to c ("Female", "Male"), in this order. R - Factors. Factors are the data objects which are used to categorize the data and store it as levels. They can store both strings and integers.
