Calculate Median of elements of a Vector in R Programming – median() Function

median() function in R Language is used to calculate the median of the elements of the numeric vector passed as argument.

Syntax: median(x, na.rm)

Parameters:
x: Numeric Vector
na.rm: Boolean value to ignore NA

Example 1:

# R program to calculate median of a vector

# Creating vector
x1 <- c(2, 3, 5, 7, 4, 8, 6)
x2 <- c(-3, -5, 6, 2, -4)

# Calling median() function
median(x1)
median(x2)

Output:

[1] 5
[1] -3

Example 2:

# R program to calculate median of a vector

# Creating vector
x <- c(2, 3, 5, NA, 4, NA, 6)

# Calling median() function
# with NA values included
median(x, na.rm = FALSE)

# Calling median() function
# with NA values excluded
median(x, na.rm = TRUE)

Output:

[1] NA
[1] 4
