An Introduction to patternplot Package

Introduction

The patternplot package is a tool for creating aesthetically pleasing and informative pie charts, ring charts, bar charts and box plots in R. It can fill pie charts, ring charts, bar charts and box plots with colors or textures or any external images in png or jpeg formats.

Versatile Pie charts

Pie charts produced by patternpie().
