# Step 1: Create a data frame or use an existing one
data <- data.frame(
Group = rep(c("A", "B", "C"), each = 50),
Value = c(rnorm(50, mean = 0, sd = 1),
rnorm(50, mean = 2, sd = 1),
rnorm(50, mean = 4, sd = 1))
)
# Step 2: Create a boxplot using the 'boxplot' function
boxplot(Value ~ Group, data = data,
main = "Box Plot Example",
xlab = "Group",
ylab = "Value",
col = c("lightblue", "lightgreen", "lightpink"),
border = "black")
# Step 3: Add grid lines for better readability
grid()
# Step 4: Add a legend to distinguish between groups
legend("topright", legend = levels(data$Group),
fill = c("lightblue", "lightgreen", "lightpink"))
# Step 5: Customize the appearance if needed (optional)
