# How to plot pie chart in R?

This recipe helps you plot pie chart in R

## Recipe Objective

How to plot a pie chart in R? A pie chart is a circular garph that represents data. It is a pictorial representation of the data. In a pie chart,the chart is divided into slices, where each slice is a proportional part of the whole data. The pie chart is a very useful tool for data analysis. This recipe demonstrates an example on pie charts.

## Step 1 - Define a vector

Syntax for pie chart plots - pie(x, labels, radius, main, col) where, x - a vector that contains the data to be plotted, labels - description that is to be given for each slice. radius(optional) - indicates the radius of the pie circle main(optional) - the title of the graph col(optional) - the color palette

``` x <- c(10,20,30,40,50) labels <- c("A","B","C","D","E") ```

## Step 2 - Plot the pie chart

``` pie(x,labels,main="Pie chart") ```
