How to Calculate the Difference Between Minimum and Maximum Yearly Rates in R

When analyzing data over several years, it's often crucial to determine the changes that occur between the lowest and highest recorded values. In this guide, we'll tackle a common task faced by many data analysts: calculating the difference between the minimum and maximum yearly rates for various diseases in a dataset ranging from 2011 to 2022.

The Problem

Imagine you have yearly data showing disease rates for a certain county from 2011 to 2022. For this example, let's take a look at a sample data frame:

You want to accomplish the following:

Group the data by Disease.

Identify the maximum rate of each disease from the most recent year (in this case, 2022).

Identify the minimum rate of each disease from the earliest year you have data for (here, 2020).

Subtract the minimum from the maximum and display the results.

If you do this correctly, the ideal output should look like this:

The Solution

To achieve this, we'll utilize the dplyr library in R, which provides a clean and intuitive syntax for data manipulation. The steps below will guide you through the process.

Step 1: Load the Required Library

First, you'll need to make sure the dplyr package is installed and loaded into your R session:

Step 3: Calculate Minimum Rates

Similarly, filter your data frame to find the minimum rate for each disease:

Step 4: Combine and Calculate Differences

Once you have both the maximum and minimum values, you can join these two data frames and calculate the difference:

Step 5: Final Output

After running the above R code, you would generate a data frame showing the differences in rates for each disease:
