How to convert string to dates in R?

This recipe helps you convert string to dates in R


Recipe Objective

The date variable/column in a dataset is of utmost importance in terms of carrying out a Time series analysis and exploratory data analysis. ​

In R, most of the times a Date-format variable is read as a character type from any dataset. If you want to carry out any sort of analysis w.r.t dates then you must convert this character type variable to date.

In this Recipe, you will learn how to convert string to Date type variable. ​

Step 1: Create a character variable

A tree is just a list which contains other lists

date_1 = "2020-05-01" date_1

Step 2: Converting to Date

We use as.Date() to convert string to Date

#converting the string to date date_conv = as.Date(date_1) date_conv
#to check the conversion class(date_conv)
