dplyr average columns

To calculate the average of multiple columns in R using the dplyr package, you can follow these steps:

1. First, load the dplyr package using the library() function: library(dplyr)

2. Next, create a data frame or select an existing data frame that contains the columns you want to average.

3. Use the mutate() function from dplyr to create a new column that represents the average of the desired columns. The syntax is as follows: new_dataframe <- old_dataframe %>% mutate(new_column = (column1 + column2 + ... + columnN) / N)

In this syntax, "new_dataframe" is the name of the new data frame that will contain the added column, "old_dataframe" is the name of the original data frame, "new_column" is the name you choose for the new column, "column1" to "columnN" are the names of the columns you want to average, and "N" represents the number of columns you are averaging.

1. Finally, you can view the new data frame with the added column by using the View() function: View(new_dataframe)

This will open a new window displaying the data frame.

By following these steps, you can calculate the average of multiple columns using the dplyr package in R.
