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: 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
