Renaming columns in R can be essential for clarity and consistency in your data analysis projects. With the dplyr package, this task becomes straightforward and efficient. Here's how you can rename columns using dplyr:
Install and Load dplyr: First, ensure you have the dplyr package installed. If not, install it using install.packages("dplyr"). Then, load the package into your R session with library(dplyr).
Select Columns and Rename: Use the select() function from dplyr to specify the columns you want to rename. Within select(), you can use the rename() function to assign new names to the selected columns. Here's the syntax:

Verify Changes: It's always a good practice to verify the changes after renaming columns. You can do this by printing the first few rows of the data frame using head(my_data) or by inspecting the structure of the data frame with str(my_data).
By following these steps, you can efficiently rename columns in R using the dplyr package, simplifying your data manipulation tasks.
