how to rename variables in r dplyr

To rename variables in R using the dplyr package, you can follow these steps:

  1. Load the dplyr package by using the library() function: library(dplyr)

  2. Use the rename() function to rename the variables of a data frame. The syntax is as follows: new_data <- rename(old_data, new_variable_name = old_variable_name)

  3. Replace "old_data" with the name of the original data frame that you want to modify.

  4. Replace "new_data" with the name of the new data frame that will store the modified variables.

  5. Replace "new_variable_name" with the desired name for the variable.

  6. Replace "old_variable_name" with the current name of the variable that you want to rename.

  7. Repeat step 2 for each variable that you want to rename.

Here's an example that demonstrates how to rename variables in R using the dplyr package:

# Load the dplyr package
library(dplyr)

# Create a sample data frame
data <- data.frame(original_var1 = c(1, 2, 3),
                   original_var2 = c(4, 5, 6))

# Rename the variables
new_data <- rename(data, new_var1 = original_var1,
                   new_var2 = original_var2)

# View the modified data frame
new_data

In this example, we have a data frame called "data" with two variables named "original_var1" and "original_var2". We use the rename() function to rename these variables to "new_var1" and "new_var2" in the new data frame called "new_data". The modified data frame is then displayed.
