How to create boxplot of vectors having different lengths in R?
If we have multiple vectors of different lengths then the boxplot for such vectors can be created by creating a single data frame using those vectors with a categorical column showing the name of the vectors and a numerical column having the corresponding values. Then boxplot function will be used as shown in the below example.
Example
Consider the below vector x and y and create the data frame using them −
Live Demo
> x<-rpois(20,2)
> y<-rpois(15,2)
> df<-data.frame(X=c(x,y),Grp=rep(c("x","y"),times=c(20,15)))
> dfOutput
X Grp
1 4 x
2 2 x
3 1 x
4 2 x
5 0 x
6 2 x
7 3 x
8 1 x
9 0 x
10 1 x
11 3 x
12 4 x
13 2 x
14 3 x
15 4 x
16 1 x
17 1 x
18 1 x
19 1 x
20 1 x
21 1 y
22 0 y
23 1 y
24 4 y
25 1 y
26 1 y
27 2 y
28 3 y
29 1 y
30 5 y
31 2 y
32 0 y
33 1 y
34 4 y
35 1 y
Creating the boxplot for groups in df −
> boxplot(X~Grp,data=df)
