months() and weekdays() and quarters(), oh my!

As a final lesson on dates, there are a few functions that are useful for extracting date components. One of those is months().

my_date <- as.Date("2017-01-02")

months(my_date)
[1] "January"

Two other useful functions are weekdays() to extract the day of the week that your date falls on, and quarters() to determine which quarter of the year (Q1-Q4) that your date falls in.
