Calculate Arithmetic mean in R Programming – mean() Function
mean()
function in R Language is used to calculate the arithmetic mean of the elements of the numeric vector passed to it as argument.
Syntax: mean(x, na.rm)
Parameters:
x: Numeric Vector
na.rm: Boolean value to ignore NA value
Example 1:
# R program to calculate # Arithmetic mean of a vector # Creating a numeric vector x1 < - c( 1 , 2 , 3 , 4 , 5 , 6 ) x2 < - c( 1.2 , 2.3 , 3.4 , 4.5 ) x3 < - c( - 1 , - 2 , - 3 , - 4 , - 5 , - 6 ) # Calling mean() function mean(x1) mean(x2) mean(x3) |
Output:
[1] 3.5 [1] 2.85 [1] -3.5
Example 2:
# R program to calculate # Arithmetic mean of a vector # Creating a numeric vector x1 < - c( 1 , 2 , 3 , NA, 5 , NA, NA) # Calling mean() function # including NA values mean(x1, na.rm = FALSE) # Calling mean() function # excluding NA values mean(x1, na.rm = TRUE) |
Output:
[1] NA [1] 2.75
