# R Programming language - R mean, median and mode

In R, the `mean()`

, `median()`

, and `mode()`

functions are used to calculate the statistical measures of central tendency.

The `mean()`

function returns the average value of a vector or set of values, while the `median()`

function returns the middle value in a vector or set of values. The `mode()`

function returns the most frequently occurring value in a vector or set of values.

Here are some examples of how to use these functions in R:

re refto:theitroad.com# Create a vector of numbers x <- c(5, 2, 8, 4, 1) # Calculate the mean of the vector mean(x) # Output: 4 # Calculate the median of the vector median(x) # Output: 4 # Calculate the mode of the vector library(modeest) mfv(x) # Output: 5 # Create another vector of numbers y <- c(5, 2, 8, 4, 1, 4) # Calculate the mean of the vector mean(y) # Output: 4 # Calculate the median of the vector median(y) # Output: 4 # Calculate the mode of the vector mfv(y) # Output: 4

Note that the `modeest`

library is required to use the `mode()`

function in R.

In addition to vectors and sets of numbers, you can also use these functions on other R data structures such as matrices, data frames, and lists. In these cases, you can specify which column or element to find the mean, median, or mode of.
