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 vectorx1 <- 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() functionmean(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 vectorx1 <- c(1, 2, 3, NA, 5, NA, NA) # Calling mean() function# including NA valuesmean(x1, na.rm = FALSE) # Calling mean() function# excluding NA valuesmean(x1, na.rm = TRUE) |
Output:
[1] NA [1] 2.75
