Program -11

11) To generate a basic box plot using ggplot2, enhanced with notches and outliers and grouped by a categorical variable using an in-built data set R

Step1 :Load required package

library(ggplot2)

Step2: load dataset

head(iris)

  Sepal.Length Sepal.Width Petal.Length Petal.Width Species
1          5.1         3.5          1.4         0.2  setosa
2          4.9         3.0          1.4         0.2  setosa
3          4.7         3.2          1.3         0.2  setosa
4          4.6         3.1          1.5         0.2  setosa
5          5.0         3.6          1.4         0.2  setosa
6          5.4         3.9          1.7         0.4  setosa

Step3: creating a boxplot.

ggplot(iris,aes(x= Species,y=Sepal.Length))+
geom_boxplot(
  notch= TRUE,
  notchwidth= 0.5,
  staplewidth=0.4,
  fill= "blue",
  color= "green",
  outlier.shape="square"
  
)+
  labs(
    title="Plotting of boxplot",
    x="Species",
    y="Sepal Length"
  )+
theme_minimal()
