Working with Dates in R: Converting, Representing, and Formatting Dates with nPlot
Understanding Dates in R When working with dates in R, it’s essential to understand how they are represented and manipulated. In this section, we’ll explore the basics of date representation in R and how to convert between different date formats. Date Representation in R In R, dates are represented as Date objects, which can be created using various functions such as as.Date(), strftime(), or mdy() from the lubridate package. These Date objects contain two main components: a numeric value representing the number of days since a reference point (the “origin”) and a character vector representing the month, day, and year.
