How to Load a CSV File in R and Name the Variable After the Filename

Loading CSV files into R is a common task for data analysis. Often, we want the variable names to correspond directly with the filenames for easy identification. Here's a straightforward way to achieve this.

Step-by-Step Guide:

Set the Working Directory
Ensure your CSV file is in the working directory or specify the path.

Load and Name Variables Dynamically
Loop through the list of files, read each CSV, and assign it to a variable named after the filename (without the extension).

This code snippet will dynamically create variables in your environment, each named after the corresponding CSV file.

Example

Assume you have a CSV file named data.csv in your working directory. The provided script will:

Load data.csv

Create a variable named data containing the data from data.csv

After running the script, you can access the contents of data.csv through the variable data.

Benefits

Clarity: Variable names directly reflect the filenames.

Efficiency: Automating the process reduces repetitive manual coding.

Scalability: Easily handle multiple CSV files.

By following these steps, you can streamline the process of loading CSV files and improve the clarity and efficiency of your R scripts.
