Date
Let’s look into the day, month, and year format specifiers to represent dates in different formats.
Example:
R
# today datedate<-Sys.Date()# default format yyyy-mm-dddate# day in monthformat(date,format="%d")# month in yearformat(date,format="%m")# abbreviated monthformat(date,format="%b")# full monthformat(date,format="%B")# Dateformat(date,format="%D")format(date,format="%d-%b-%y") |
Output
[1] "2022-04-02"
[1] "02"
[1] "04"
[1] "Apr"
[1] "April"
[1] "04/02/22"
[1] "02-Apr-22"
How to Use Date Formats in R
In this article, we will be looking at the approaches to using the date formats in the R programming language,
R programming language provides several functions that deal with date and time. These functions are used to format and convert the date from one form to another form. R provides a format function that accepts the date objects and also a format parameter that allows us to specify the format of the date we needed. R provides various format specifiers which are mentioned below in Table-
