Real-world Use Case 

Here is an example of how you might use data mining in R with a case study. Suppose you are working for a healthcare company and you want to use data mining to identify potential risk factors for heart disease. You have a dataset containing information about patients, such as their age, gender, BMI, and blood pressure.

To begin, you will need to install and load the necessary R packages for data mining, such as caret for training and evaluating machine learning algorithms, ggplot2 for visualizing data, and dplyr for data manipulation. You can do this using the install.packages() and library() functions, as shown below:

# Install the caret, ggplot2, and dplyr packages
install.packages(c("caret", "ggplot2", "dplyr"))

# Load the caret, ggplot2, and dplyr packages
library(caret)
library(ggplot2)
library(dplyr)

Next, you will need to load the dataset containing the patient information into R and explore it using the ggplot2 and dplyr packages. For example, you can use the ggplot() function to create scatter plots of different variables, and the filter() and select() functions from the dplyr package to select and manipulate the data.

# Load the dataset into R
patient_data = read.csv("patient_data.csv")

# Explore the data using ggplot2 and dplyr
ggplot(patient_data, aes(x = age, y = BMI)) + geom_point()
patient_data %>% filter(blood_pressure > 120) %>% select(age, gender, BMI)

Once you have explored the data and identified potential risk factors, you can use the train() function from the caret package to train a machine learning model that can predict the likelihood of heart disease based on the patient’s age, gender, BMI, and blood pressure. For example:

# Train a random forest model using the patient data
model = train(heart_disease ~ age + gender + BMI + blood_pressure, data = patient_data, method = "rf")

# Use the model to make predictions on new data
predictions = predict(model, newdata = patient_data)

This code trains a random forest model using the patient data and then uses the model to make predictions on the same data. You can then evaluate the performance of the model using various metrics, such as accuracy, precision, and recall. If the model performs well, you can use it to make predictions about new patients and identify potential risk factors for heart disease.

To continue with this case study, you can use the trained model to make predictions on new data and evaluate its performance. For example, you can use the confusionMatrix() function from the caret package to compute various metrics, such as accuracy, precision, and recall, and the plot() function to visualize the results.

# Evaluate the performance of the model using a confusion matrix
results = confusionMatrix(predictions, patient_data$heart_disease)

# Print the accuracy, precision, and recall of the model
print(paste("Accuracy:", results$overall[1]))
print(paste("Precision:", results$byClass[1]))
print(paste("Recall:", results$byClass[2]))

# Visualize the confusion matrix using ggplot2
ggplot(results$table, aes(x = Reference, y = Prediction)) + geom_tile(aes(fill = Freq))

This code computes the accuracy, precision, and recall of the model using a confusion matrix, and it visualizes the confusion matrix using ggplot2. If the model performs well, you can use it to make predictions about new patients and identify potential risk factors for heart disease. You can also try using different machine learning algorithms or adjusting the model parameters to improve the performance of the model.
