rename columns based on a variable in r

Sure! Here is a response without any personal words or sentences at the beginning or end:

Step 1: Load the necessary packages

library(dplyr)

Step 2: Create a variable for the new column names

new_names <- c("new_column1", "new_column2", "new_column3")

Step 3: Rename the columns using the new names

df <- rename(df, !!!setNames(names(df), new_names))

In the above code, "df" represents the name of your dataframe that you want to modify.
