How to Change Datetime Format by Removing the Seconds

When working with datasets in R, you may find yourself in a situation where datetime data is presented in a format that doesn't suit your needs. One common issue is having datetime data in yyyy-mm-dd hh:mm:ss format, but you only require it in dd-mm-yyyy hh:mm format—essentially eliminating the seconds. This guide will walk you through how to accomplish this in R with simplicity and clarity.

Understanding the Problem

Let's break down the problem. You have a dataset containing datetime entries, and they are structured in a way that includes seconds. For instance, your datetime data looks like this:

You would like to convert it to:

As you can see, the format has changed: the order of the day, month, and year is now reversed, and seconds have been excluded.

The Solution: Using the format Function

R provides a convenient function called format that can be used to alter the way datetime objects are displayed. Here’s how to use it effectively:

Step 1: Prepare Your Data

First, ensure your datetime data is in the correct format. Below is an example of how your data is structured in R:

Step 2: Use the format Function

Next, apply the format function to convert the datetime entries. The format string you want to use is "%d-%m-%Y %H:%M" which specifies how the output would look. Here’s the code you’ll need:

This line of code will produce the following output:

This output confirms that the seconds have been successfully removed and the format has been adjusted as desired.

Conclusion

Modifying the datetime format in R is straightforward with the format function. By specifying the appropriate format string, you can achieve clarity and conciseness in your dataset. This is particularly helpful when preparing data for reports or visualizations, ensuring that your datetime information is presented in a reader-friendly manner.

We hope this guide has provided you with the necessary tools to change your datetime format effectively, helping you get the most out of your datasets in R.
