R Pie Charts

🥧 R Pie Charts

In R Pie Charts is used to show how a whole is divided into parts.

Each slice represents a proportion or percentage of the total.

 1. Basic Pie Chart

Use the pie() function.

R

values <- c(40, 30, 20, 10) labels <- c("A", "B", "C", "D") pie(values, labels)

1 2 3 4

values <- c(40, 30, 20, 10) labels <- c("A", "B", "C", "D")   pie(values, labels)

 2. Pie Chart with Title

R

pie( values, labels = labels, main = "Simple Pie Chart" )

1 2 3 4 5

pie( values, labels = labels, main = "Simple Pie Chart" )

---

 3. Pie Chart with Colors

R

colors <- c("red", "blue", "green", "orange") pie( values, labels = labels, col = colors )

1 2 3 4 5 6 7

colors <- c("red", "blue", "green", "orange")   pie( values, labels = labels, col = colors )

 

---

 4. Pie Chart with Percentages

R

percent <- round(values / sum(values) * 100) pie( values, labels = paste(labels, percent, "%"), col = colors )

1 2 3 4 5 6 7

percent <- round(values / sum(values) * 100)   pie( values, labels = paste(labels, percent, "%"), col = colors )

 

---

 5. Exploded Pie Chart

R

pie( values, labels = labels, col = colors, radius = 1, init.angle = 90 )

1 2 3 4 5 6 7

pie( values, labels = labels, col = colors, radius = 1, init.angle = 90 )

📌 R does not support explode directly, but radius and angle help visually.

 6. Pie Chart from Data Frame

R

df <- data.frame( category = c("Math", "Science", "English"), marks = c(80, 70, 90) ) pie(df$marks, labels = df$category)

1 2 3 4 5 6

df <- data.frame( category = c("Math", "Science", "English"), marks = c(80, 70, 90) )   pie(df$marks, labels = df$category)

 

---

 7. 3D Pie Chart (Extra Package)

R

# install.packages("plotrix") library(plotrix) pie3D(values, labels = labels)

1 2 3 4

# install.packages("plotrix") library(plotrix)   pie3D(values, labels = labels)

 When NOT to Use Pie Charts ⚠️

❌ Too many categories
❌ Comparing small differences

✔ Use bar charts instead in such cases
