How To Get Mean Of A Column In R

The mean of a column in R can be calculated using the mean() function. The Mean() function takes a column name as an argument and calculates the average value of that column. Average of one column in R, Average of many columns in R using dplyr. Get row wise mean in R. Let’s see how to calculate Mean in R with an example

  • Mean value of single column in R function – mean()
  • Average of multiple columns in R
  • Average of multiple columns in R using dplyr
  • Find Average of a column by column name
  • Find the Average of the column by column position
  • Receiving goods means being wise in CHEAP

First let’s create the data frame.
