Count Number of Values in Range in R (Example)


In this R article you’ll learn how to get the number of observations within a certain range of values.

The page is structured as follows:

Let’s dig in.


Introducing Exemplifying Data

Have a look at the following example data:

x <- c(3, 1, 6, 5, 6, 3, 4, 4, 8, 2)    # Create example vector
x                                       # Print example vector
#  [1] 3 1 6 5 6 3 4 4 8 2

Have a look at the previous RStudio console output. It shows that our example data is a numeric vector containing several integer values.


Example: Get Number of Observations in Certain Range Using > & <

In this example, I’ll explain how to count the number of values in a particular range.

For this, we can use the larger than (i.e. “>”) and smaller than (i.e. “<”) operators as shown below:

sum(x > 3 & x < 7)                      # Count cases in range
# [1] 5

The RStudio console returns the result: Five elements of our vector lie in the range between 3 and 7.

On this page, I have illustrated how to count the number of cases in a specific numeric range (i.e. greater than particular value A and smaller than particular value B) in R. Don’t hesitate to let me know in the comments section, if you have additional questions.
