How to create boxplot using ggplot2 without box border in R?
We know that the middle portion of a boxplot is a box which is covered with black border but we can remove that border from the plot by defining the aesthetics of the boxplot with color argument. We can follow the below steps to create such type of boxplot −
- Creating a data frame.
- Then create a default boxplot.
- Loading ggplot2 package and creating the same boxplot without box border.
Create the data frame
Let's create a data frame as shown below −
x<-sample(LETTERS[1:4],20,replace=TRUE)
y<-rnorm(20)
grp<-sample(c("Male","Female"),20,replace=TRUE)
df<-data.frame(x,y,grp)
dfOn executing, the above script generates the below output(this output will vary on your system due to randomization) −
x y grp 1 C -2.03011561 Male 2 A -0.11006189 Female 3 D 1.14021182 Female 4 A 0.13282948 Male 5 C 1.24059685 Female 6 A -0.64027706 Female 7 D 2.69644400 Male 8 B -0.16214751 Male 9 C -0.57809399 Female 10 B 1.13308146 Female 11 A 0.09518827 Female 12 D -0.49467890 Female 13 C -2.07383434 Male 14 A 0.48415726 Male 15 C -0.85017870 Female 16 B -1.39666444 Female 17 A 1.61422362 Male 18 C 0.44615237 Male 19 D -1.35304529 Female 20 C -0.56352488 Male
Creating the default boxplot
Loading ggplot2 package and creating the boxplot for categories in grp column −
x<-sample(LETTERS[1:4],20,replace=TRUE)
y<-rnorm(20)
grp<-sample(c("Male","Female"),20,replace=TRUE)
library(ggplot2)
ggplot(df,aes(x,y,fill=grp))+geom_boxplot()Output

ggplot(df,aes(x,y,fill=grp))+geom_boxplot()+geom_boxplot(aes(color=grp))Output
