Parsing and formatting dates
An essential early step in working with "raw" time series data (usually a data frame column or vector of observations) is to make sure all of your dates are in the same "date format". This is especially true when your data comes from multiple sources.
In this exercise, you'll practice formatting dates
in two ways, using lubridate
. First, you'll convert the dates
object, a character
vector, into a vector of class Date
. Second, you'll reformat dates_order
, an object which contains inconsistent date formatting.
The dates
and dates_order
objects, and the lubridate
package, are loaded for you.
