Working with dates and times

In a?recent post on LinkedIn, I mentioned that one goal of?Empirical Research in Accounting: Tools and Methods?(co-authored with?Tony Ding) is to provide a pathway to mastery of the contents of?R for Data Science.?

In that post, I identified a few gaps, including spreadsheets, hierarchical data, and dates and times that I planned to cover in a series of notes.?A recent note?covered hierarchical data and a forthcoming note will address spreadsheets.

The note here addresses the gap regarding dates and times. It includes details not covered in the?“Dates and Times” chapter?of?R for Data Science and also a hands-on application based on the SEC submissions data I discussed in?the note on hierarchical data.
