R: Pie Chart

I. Constructing a Basic Pie Chart

The following data, regarding their preferred dessert, was collected from patrons at a local restaurant.

The following R code will use the pie() function to construct a pie chart for this data.  

# SIMPLE PIE CHART
slices = c(23, 12,18, 21, 33)

# DEFINE LABELS - ORDER IS CORRELATED TO NUMBERS ABOVE
dessert = c("Ice Cream", "Pudding", "Apple Pie", "Cookie", "Cake")

# CONSTRUCT PIE GRAPH
pie(x = slices,
    col = heat.colors(5),
    labels = dessert, 
    main="Pie Chart of Preferred Dessert")
