Last Updated : 15 Jul, 2025

**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 Vectorna.rm: Boolean value to ignore NA value

Example 1:

Python3 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:

Python3 1== `

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
