# Step 1: Load necessary libraries
library(tidyverse)

# Step 2: Read the data from a CSV file
data <- read.csv("your_data_file.csv")

# Step 3: Explore the structure of the data
str(data)

# Step 4: Check summary statistics
summary(data)

# Step 5: Clean and preprocess the data (if needed)
# Example: Remove missing values
data_clean <- na.omit(data)

# Step 6: Create visualizations for data exploration
# Example: Histogram of a numerical variable
ggplot(data_clean, aes(x = numeric_variable)) +
  geom_histogram(binwidth = 10, fill = "blue", color = "black") +
  labs(title = "Histogram of Numeric Variable",
       x = "Numeric Variable",
       y = "Frequency")

# Step 7: Perform statistical analysis
# Example: t-test between two groups
t_test_result <- t.test(numeric_variable ~ group_variable, data = data_clean)
print(t_test_result)

# Step 8: Create a new variable or transform existing ones
# Example: Create a new variable based on a condition
data$new_variable <- ifelse(data$old_variable > 5, "High", "Low")

# Step 9: Save the cleaned data to a new CSV file
write.csv(data_clean, "cleaned_data.csv", row.names = FALSE)
