Dates

Dates are a special type of data in R, and are distinct from the date types POSIXct and POSIXlt, which represent calendar dates and times in more formal ways.

Let's create and check the class() and typeof() of different date objects in R. Follow these steps:

1. Create the objects using the following code:

e <- as.Date("2016-09-05")f <- as.POSIXct("2018-04-05")

2. Check the class and type of each by using class() and typeof(), respectively, as follows:

class(e)typeof(e)class(f)typeof(f)

Output: The preceding code provides the following output:

One nice thing about R is that we can change objects from one type to another using the as.*() ...
