R Pie Charts

This lesson is part of R · All levels

Summary

This lesson discusses the creation of a pie chart in R using the function pie(). A circular diagram is used to show the percentage proportion of complementary categories to the total 100%. The developer will learn to set up the percentage labels, play the initial orientation, and select the color palette.

Key points

The 'pie(vektor_nilai, labels = vektor_label)' function creates a circular diagram
The col argument stains every piece of the circumference of the circle
The 'init.angle' argument determines the starting angle of the cutting diagram
Although popular, pie charts should be limited to small categories so as not to be difficult to distinguish.
