get_date: Create a date from NOAA data given DAY, MONTH, YEAR

In dannyjwpark/NOAA: NOAA Earthquakes

Description

The NOAA data has columns called DAY, MONTH, YEAR. Part of the requirements for cleaning this data is to create a date column. All of the years are provided, but some of the months and days are NA. We'll replace NA days with 1st and NA months with Jan. Also, note that as.Date does not play nice with negative years, so these have been removed. Vectors days, months and years must be of the same length.

Usage

get_date(days, months, years)

Arguments

days	Day of the year as integer vector
months	Month of the year as integer vector
years	An integer vector of years

Value

A vector of the date objects returned from passing date strings to as.Date
