# R Programming language - R min() and max()

www.igiftidea.com

The `min()`

and `max()`

functions in R are used to find the minimum and maximum values in a vector or a set of values.

The `min()`

function returns the smallest value in a vector or a set of values, while the `max()`

function returns the largest value.

Here are some examples of how to use `min()`

and `max()`

in R:

# Create a vector of numbers x <- c(5, 2, 8, 4, 1) # Find the minimum value in the vector min(x) # Output: 1 # Find the maximum value in the vector max(x) # Output: 8 # Find the minimum and maximum values in a set of numbers min(5, 2, 8, 4, 1) # Output: 1 max(5, 2, 8, 4, 1) # Output: 8

You can also use the `na.rm`

argument to exclude any missing values (NA) from the calculation. For example:

# Create a vector with missing values y <- c(5, 2, 8, NA, 4, 1) # Find the minimum value in the vector, excluding missing values min(y, na.rm = TRUE) # Output: 1 # Find the maximum value in the vector, excluding missing values max(y, na.rm = TRUE) # Output: 8

In addition to vectors and sets of numbers, you can also use `min()`

and `max()`

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 minimum or maximum value of.
